doggy... cant you just tune one map for 75-100% throttle and just have emanage interpolate the rest of the corrections?

Lagos - tuning for the WOT - its not a problem - cuz you basicly are tuning at only last to rows of the table - but adjusting Cruise mode - its was hard... Cuz driving condition might change instantly - while the same might happen with the boost - so we had to find optimum mode and tune it up... Its still the car runs at about 11.5-12.5 A/F ratio on Wideband, so its on the very safe side... Sometimes while cruising it hits 10 mark so its abit too rich - but atleast it is safe... Aint gonna talk about fuel consumptions...

What plugs are you using?

ive never used the emanage, so these are more like retarded questions then they are advice...

but, when you tune for cruise, can you just bump down the injector duty cycle far enough to where you see your o2 sensor start to kick in and let the ecu figure out how to take it to a stoich cruise or idle ? then interpolate from there, to your WOT run to make a smooth transition?

[trd94]

so does the 2 bar map help or does it not really matter as far as using the emanage,

[TomPoz]

Well done, Romas. Numbers are impressive. Can't wait for pics and dyno charts, but even more for Martin to come to me and show me "The Beast".

[presure2]

I let the numbers speak for me

High Boost mode (0.9 bar) 206hp / 296Nm

Low Boost mode (0.5 bar) 176hm / 225 Nm

At 0.9 bar - its imposible to handle it - first of all - wheels spin is crazy (on 14" winter tires - you can imagine ). 2bar map from ST205 - Aint made any changes in our tuning - cuz DAMN EMANAGE makes adjustments ACORDING damn TPS sensor - and only Ignition table is based on MAP.... So stock 7A map at 0.5bar - read 5v... So corections can be done with the Emanage to avoid Check engine... But the problem is what is its damn hard to tune the car cuz TPS sensor and Boost are 2 totaly different thing - and Boosting isnt related to a TPS 100%... Cuz at the one position of trotle boost might be at one number, and in other case - at other nuymbers... So it was HARD to find optimum adjustments what the car would drive normaly...

Now - everything is finally finished - tomorow will be positing Pics and Dyno Sheets...

BTW - martin is on the way here already

nice job romas.
hell if the emanage blue can only do fuel correction based on TPS, its not very good for tuning for boost. with the EM ultimate, you can choose which signal its based off. you can use the map voltage, boost pressure, or TPS.

Oook Here are the final pics of the enine bay and some goodies. Its 7.30am in the morning and after 1 hour im gonna drive to pic up Martin from other city and drive back here for him to see his car and start his journey back home Im still waiting for the Dyno sheet from the dyno guys, i asked them to send it by email...

As for now - enjoy:

[Batman722]

Looks great Romas, my hat is off to you.

you know the first thing Martin is gonna do is paint that valve cover red...

how's the tune for daily driving ? get that sorted out ?

[j0e_p3t]

that is teh sex. major kudos to you mr romas. hands down the best 7afte i've seen. martin's one lucky guy. you should get a video of his reaction when he sees it and post it here.

Thanks Dustin I hope he aint gonna do what you said Daily driving is 98% sorted out - its sometimes running a bit too rich - but this might be cuz of the Plugs / really cold weather / and having no chance to tune it up on the road cuz roads are all Icy - so no grip on the wheels and no road force acting on the wheels... But its drivible

Nice Romas! Good work. I'm surprised that you've been able to boost 12.5. I was always thinking you could only hit that much with a fully built 7AFE. But I guess it depends on how you build your setup. And you did good Romas! I hope the dyno results are a happy one.

[TomPoz]

The beauty and the beast. Respect Romas, as usual.

Well, you guys can expect more pics from my planned meeting with Martin on his way home.

Martin is already on the way to ya Tom Just dont get crazy with the car and Boost - let him get home first And on the High Boost mode - the clutch is crying

I will be waiting for the pics and responses from your side once he gets to ya

The people who never even had experience with a turbo 7A started that silly rumor. I've boosted 15 PSI untuned many times and the engine is as good as it ever was. Compression is still 220-220-215-220.

[phonex98]

sorry if im OT a bit here, but is 220 the best possible compression for the 7aFE ? Also, if someone has extra time, could you tell me or direct me to a site that tells me approximately how compression numbers are derived ? (Ie. Is it a function of stroke length, volume... what ?) Thanks!

P.s. Doggy, you are inspiring me to turbo

So Martin arrived few hours ago. I saw the beauties (Martin's GF and Celica ), the beast (engine) and its heart (turbo). Impressive. We had a small meet with my club buddies and drove home. I was testing Martin with my 320 Nm car but he did not fall behind. Tomorrow after breakfast I will take a closer look at the car in daylight and share my experience with you later on.

yeah i hit 17psi a few times ,the motor loves the boost but my valve cover seal did not i plan on running 15psi daily once i am done only time will tell

[lagos]

does the 7afe have a knock sensor?
