3sgte problem, cant get over 4000 rpm Options

[thedevilmaycrie]

ok heres the thing i just finished my engine swap...... all vac lines are hookes up right...... electrical checks good...... engine is outta a mr2 jdm..... can anyone tell me what the hell is going on ..... on the interstate once i get to 4k rpm the engine starts cutting out like its the fuel is being cut off and i cant reach over 4.5k before the engine wont go any higher...... any thoughs .... any?

[Supersprynt]

I have the SAME problem, I havent started looking into it i've been too busy but as soon as things calm down im ripping it apart again. But if uget anywhere, IM me "Supersprynt" we'll work together on it.

check the 2bar map sensor.. do they go bad?

[XSTeknique]

Atleast you guys can drive your cars. Mine won't start, so I've yet to find out if I can go over 4k or not. Did you guys have Mike do your harnesses too? Just curious, wondering how many other people had their's done by him.

[97sccelica]

[Supersprynt]

I did it myself but Mike provided the diagram to which i did it, so its according to how he does it. I've asked Mike about it and he said ignition problem and perhaps something with the tach, but he doesnt really know. I was HOPING a cold solder, but now that he has the same problem...i dunno.

I have a rev/speed meter, and when it approaches that point where it cuts off, the tach stays a constant 4000-4.5K but the RSM gets lower as it gets closer. Its weird.

And XS, did you do a spark test to see if your even getting spark? You gotta eliminate it one by one, fuel, spark and oxygen create combustion. So check ur fuel pump, ur solenoid, ur distributor, ur AFM. Mine didnt start the very first time but its cuz i was missing the solenoid...after that it started right up.

Only thing is you have an MR2, which is like a 91-92 3sgte, i have a 92/93 3sgte, and yes they do differ in wiring.

[Jabberwock]

hmm....I am not sure but can it have anything to do with the AFM....

[lagos]

guys, talk to thats_right on celica.net. i remember him having the same problem and he got it fixed. before he fixed it he said that he thought it was the dist cap and rotor, but im not sure if thats what it was in the end.

[thedevilmaycrie]

hey guys i gotta idea has anyone added a boost-a-pump or a high pressure pump cause the 5sfe runs a lower pressure then the 3sgte and it only happens at high rpms

[kuya1284]

[Supersprynt]

It happens at 4 - 4500 RPM's which, for the 3sgte, is low because max hp is at 6.

And what is happening is a complete halting of the engine, how can the fuel pump work fine sub-4 and doesnt work at all above? I dont get it ?

Also, i've replaced the dist. cap, ignition coil, and spark wires, and plugs, no effect.

[NEVERSTOP]

I never had a problem like this before with my straight 205 but now that I am doing the 185 topend on the 205 block I will need a harness done, and have been thinkin about havin mike do it.. I'm really curious if its something to do with how the harness is done or is it just a coincedence..

what PSI of boost is your cars at when it shuts down.. stock 3sgte will do a fuel cut a 16 psi ( I think thats when it is ) that could possible be your prob

[Supersprynt]

I think its 12psi max and mines running 8.5 right now. It wont go over in neutral or driving.

The check engine lights does come on when it happens, but goes off right after...so I'm gonig to check the codes to see what the ecu is telling me.
Ne body know the website that lists 3s ecu codes?

[thedevilmaycrie]

super mine is doing the same damn thing with the check light im leaning toward my suggestion of the fuel pump

[Supersprynt]

Check ur engine code see if it tells you anything

[XSTeknique]

No, I don't have an MR2 motor. It's out of a ST185. Thanks for the tips guys...we're checking...

[sphinx]

well, i dont know if anyone remember or not, or even cares for that matter, but i am having issues with getting mine started.

my motor is from a jdm st185, and i know i'm missing the EFI solenoid. BUT NOT ANY MORE.

Despite all the bad rap that ToySport gets and all, and i know for a fact that they are a bunch of pricks, i was down to my last resort, so i called them up about the solinoid, and joel said that he had one. This was yesterday. Today at lunch time, i went over there, and long behold, he had one. He gave it to me for $50.

So now i just have to hook it up and hopefully my car will start.


*preys*

[Supersprynt]

Yeah thats where i got my solenoid, and i had to deal with Joel too, but he did keep calling me back to make sure he had the right part.

And my engine is an JDM ST185 3s too.

[thedevilmaycrie]

ok i gotta possible solition a guy i met had the same damn problem.... well its not actually a "solution" but it makes the problem go away.... when he did his swap his boost controler was set to scramble so he reset it to stock or off and it went away he lost power but it would run ..... now i have no idea how to set the boost controler hell i didnt know the 3sgte stock had a controler if anyone knows how to set it or such lemme know

[Supersprynt]

Huh? I have never heard of a stock boost controller, and why didnt u ask how he did it?

I've unplugged my battery and everything usually taht resets the ecu but it hasnt gone away.

Also, my car is running stock boost, i have a gauge and it shows 8 - 9 depending on how hard its being pushed.

[97sccelica]

try getting a fuel pressure gauge and hooking it up to see if you are fuel cutting. at 4krpm

[Supersprynt]

Yeah i was going to be getting one with my Lotek 3 gauge pillar so this should help. I'm going to get the ecu codes soon.

[Supersprynt]

I'm going to try to read the codes this afternoon...
this problem must be fixed by spring.

[XSTeknique]

Hey just curious, you guys that are missing parts...i'm assuming you didn't buy a clip? Because it just wouldn't make sense to be missing parts if an entire clip was purchased. Ya got me all worried is all, that's why i'm asking.

[kuya1284]

[thedevilmaycrie]

my clip had everything from the wire harness to all the vacume lines

[XSTeknique]

Yes, I can vouch for the damaged parts. Jarco sent me a nicely fried ECU. No dis on the company though, they've been great nonetheless.

[Supersprynt]

UPDATE: read the codes outta my ecu, 14 and 35 is what i got. Now theres a chart on alltrac.net that says 14 is "no IGF signal to ECU 8-11 times" and 35 is "Open or short ciruit in pressure sensor". Now I think these codes are for the ST165 however the absense of a IGF signal would make sense, its what Mike was saying also.

The pressure sensor, well we dont have them in our stock cluster so thats always going to be a problem, but the IGF i think is the problem. It would account for my weird problem with the RSM.

If you'd like to check ur own codes, use a paper clip and stick one end in the E1 and one end in the TE1 in the diagnostics box in the engine compartment. If you wanna double check ur codes against mine it would probably pinpoint the problem.

[Supersprynt]

Ok well i started playing with this. I checked the ECU pinout and looked over my wiring. The RSM is wired to the IGF would explain why it goes nuts when it gets close. So i took that out cuz maybe it was doing something and i hard wired it, didnt solder tho, and i started it and tried and nothing happened. Gave me the same codes and so i followed the wire back to the igniter. Now i dunno whats going on i have the stock GT ignitor cuz the plug for the 3sgte fits on it and I dunno if thats the problem. The wiring maybe different but for now im stuck.

[ToYCeLi8]

[Supersprynt]

I will be getting the AVCR, u like it?

[Digndoug]

Im sure you guy's thought of this, but i had a similar thing happen to my old car, it wasnt turno, but when i would hit certain rpms it would shut off, it could be your fuel shut off is set up wrong, like when a car is speed limited, its just a fuel shut off, or it could be in your comp...just a thought

[Supersprynt]

Fuel generally will shut the car off so that the gas pedal wont operate, in this case, its similar to a rev limiter. I was flooring it yesterday and it just stays up there, but wont go over it. Its just weird that the both of us have that problem.

[kuya1284]

[Supersprynt]

Yeah I am going apexi... I have the RSM and TT.

[Supersprynt]

Ok someone on Celica.net answered some of my questions. 1 i have the wrong igniter, I have the ST204 igniter and i need the St185 igniter, this maybe the problem, but also that the pressure sensor is necessary to retard timing and add fuel, so that may also be the problem...

now i just need to fix it.

[thedevilmaycrie]

any ideas on how to fix it? im a little new to turbos

[Supersprynt]

Well first off. what igniter are u using on your swap?

I'm going to swap my igniter to an St185, its about $250 for it.
If that doesnt work im going to make sure the wiring on the pressure wire is ok, no shorts or breaks and then if that doesnt work im going to have to replace the pressure sensor.

Mine is up and running.... 97 mr2 engine and tranny....

how do i increase my photo limit... i wanna upload more photos.

[thedevilmaycrie]

ok sounds good im using a mr2 igniter..... but one problem how is it that so far 3 have had the same problem mine and yours are the EXACT same though and how could it be the wires in that case i think that theres a hidden factor that were not seeing... i seached the net today and found some stuff

http://www.alltrac.net/mods/fuelcut.htm
http://jekylandhyde.madpowaz.com/knock.htm

tell me what yall think

[Supersprynt]

Check ur engine codes, we may have different problems with similar effects.

If you have the same error codes as i do, we can narrow it down.

[thedevilmaycrie]

tell me exactly how to check the codes i know about the paper clip but do i just turn it on after that? and what are the check engine codes for your problems?

[Supersprynt]

if u've had ur battery disconnected rev ur car til the engine light comes on and then turn it off. Find the diagnostics box and put one end in the E1 and one in the TE1, the locations can be found in the top of the box. Once those are in place, turn ur car on, dont start it, and the engine light should begin to blink.

It'll blink a certain number of times, a short pause, and then blink again.
The first set of blinks represents the first number in the code, the second represents the last such as:
* = blinks
***......****... that would equal 34.
A longer pause will be between different sets of codes, and the longest will be when it repeats itself.

Now the only thing that you might have trouble with is deciphering the codes. I dont kno if the MR2 ECU codes are the same as the Celica ECU codes. The website I went to to match them up is HERE.
This website should be bookmarked to ALL ST185 owners as it is a very useful website.

[thedevilmaycrie]

i fixed the problem i removed the vsv for the turbo outta the equasion the vsv is under the intake maniflod i took a pen cut it in half and put the two lines straight together and left he vsv connected electicaly and i have full rpms!!!!!!!

[Drocay]

Good Stuff man, congrats.

[kuya1284]

[97sccelica]

[Supersprynt]

Whoa whoa PM me or EMAIL Me (Supersprynt@rcn.com) and lemme know exactly what you did!!!

Did ur engine codes tell you it was something with that VSV or did u just guess?

This post has been edited by Supersprynt: Dec 20, 2003 - 10:02 AM

[Supersprynt]

bump?

[thedevilmaycrie]

i read a web page telling me about it and its effects so i did it outta curiosity and boom i started reved had full rpm and hit the road running.... all i did was diconnect the two vacume lines that went into the vsv and connected them together using (haha) a pen i cut in half

[kuya1284]

[Supersprynt]

Well I will be getting the EBC by Apexi sometime or another so this will have to be done anyways.

What did you take off exactly? Just the heat shield on the dp?

also, do u have that website where u read that.

[qatar11]

Hey Bryan -


Before I embarrass the both of us here in the boards... whats goin on?

[Supersprynt]

You mean the problem? Its the one i was talkin to you about, sputtering at 4000rpm's, weird thing with my RSM...

[qatar11]

NO

[Supersprynt]

ohhhhhh k

[Supersprynt]

Yeah so I disconnected my VSV, and it didnt do sh!t for me, still has the same problem.

[celica3sgte]

So it sounds like you guys were hitting the fuel cut. As soon as the ecu is sent a 4.4 volt signal, which is 12.8 lbs of boost, the fuel defense system is initialized. Bypassing the vsv never lets the computer see the voltage. What are your boost gauges reading? What state do you live in? Hey supersprynt, get on ebay and find some people sellling 3sgte motors and clips. EMail them, b/c they may have an ignitor for much cheaper than $250.

[Supersprynt]

I just bought one for 45 and its not fuel cut b/c of boost cuz im only boosting 8.5 - 9.

[Supersprynt]

ITS FIXED ITS FIXED, HALLELUJA ITS FIXED!!

I needed a turbo ignitor, which got for $45 and its a $250 part, a fully operational 3S-GTE is now in my posession...now i just gotta wait til spring to drive again.

[GeEkBoY]

congratts

gonna be a long winter for you now

[sphinx]

glad you finally got it working properly.

but why do you have to wait so long to drive it?

[LatinKraze]

same question here? I personaly wouldnt be able to wait to ride her.

[Supersprynt]

Well I dont drive her in the winter, in October i bought a 2000 Rodeo and because of the Celica's problem and the fact that its a custom car, i dont want it touching snow or salt or sand so i pull it off the road, and switched the plates to the Rodeo. So right now its unregistered sitting in my garage.

I was driving it when i first finished it, but I couldnt go over 4K RPM, which is awful.
