Forged st205 GT3082r on STOCK ecu possible???, Help!!! Options

[Dudleydaftdog]

Hi All,

Just wondered if Amy of you guys could please shed some light on my problem...

I have a forged st205 and was running a hks f con v pro with sard 800s and a gt3082r turbo. My F con has died!!! Had to refit the stock 550 injectors (running at 4 bar (closer to 650s) on the STOCK. ecu. Ext WG spring is only set @ 8 psi.

Question:

Has anyone ever tried this before? (Read TRDGT4 tried it but doesn't say what GT30 turbo in the old thread)

Basic engine wpec

St185 bottom end, 8.2CR, Forged pistons and rods, ACL race series everything, ARP everything, hks 256 cams, cosmetic 1.5mm hg, Kevlar cambelt, meth ink, JUN valvetrain, FMIC, 3 inch decay as exh etc etc..

If anyone could please advise me is be really grateful. Seems to drive fine off boost (wideband between 14-15), tips in a bit lean, just scared to boost!!!!!

Thanks in advance

Chris

dont boost. you answered ur own question

set your wastegate to the lowest spring ugot and keep ur foot off that pedal

8 psi on a GT30 will be fine on a stock ECU. just keep the boost to a minimum

Thanks for both your paleoreplays guys, your wisdoms appreciated. Think I'm gonna take Delusionz advice and play it safe till I can get my fcon fixed (hks won't sell the part I need to my tuner).

Can't see it running lean at 8 psi even tho there's more flow because I'm running a Waldron, swirl pot, Bosch 044, twin fed rail @ 4 bar on a sard for on the stock 550s (650s @4bar). Thinking I could use the GM ist sensor I have spare in the garage that reads colder than the own Toyota sensor to compensate for the MAP sensor/extra flow? It reads roughly 20 degrees lower so would add more fuel at the same pressure?

What's the biggest turbo any of you guys have ever run first hand on the stock ecu?

Could be months till the ecus fixed and will HAVE to use the car unfortunately. Hoping to get a replacement F con S next month so fingers crossed this should be sorted soon. Please keep your thoughts coming, I really appreciate it.

Thanks

Chris

cant u find a powerfc or something?

Wish I could, only one I've seen around, is £800 on eBay. Managed to get a ct20b second hand for 100 but is gonna be a pain to refit and is a step backwards if I do in terms of what I wanted to build...

Only prob I've had so far on the stock ecu is that I'm runnining lean just before spool up. No hesitation or anything just in the 14s on my wideband instead of 13s where it should be. Listened to your advice and have not been above 4 psi...

Still not managed to the part for my fcon cos hks won't help my tuner. My tuners said he CAN fix it but might be a week, might be 6 months...

Fitted a gm temp sensor I had spare to try and add fuel. Any ideas for dropping afr whilst in closed loop?

Thanks for all your help : )
