1G turbo conversion wont rev past 3000rpm

[4g63knock]

I got a 92 talon N/T, i have done a conversion to turbo i been working on this car for the past month 1/2 and cannot find why it doesnt rev past 3000rpm. i bought stock turbo ecu, ecu+ piggyback, 450cc 1g injectors and resistor pack and GM3 Mass air sensor plus all the accesories, i have check all the wiring step by step and everything looks fine, the last thing i can think is the throttle body, i dont know if i need a turbo one. CAN SOMEONE PLEASE HELP ME WITH THIS. THANX IN ADVANCE

Neh the throttle body doesn't matter, I ran my converted n/t w/o the turbo throttle body just fine...I'm assuming you have a maf-t for that GM mas right?

 

[4g63knock]

No i dont have a maf-t but i got the ecu+ it works like the translator, the two other things i dont have from the stock turbo car is the wg/solenoid and the by pass valve i am not sure if that woud have something to do with it, i do have a aftermaket BOV. it just confusing bro, thanx for you help. I just got doing an on board diagnostic with my ecu+ and this is what i found CODE 12 intake air flow sensor does that means is bad?

But Rx3, it's a 1g.... That means it's a 4g63 N/A.

did you ran that extra wire for the maf sensor to the ecu?

 

[4g63knock]

this conversion is driving me crazy, since ya all know the gm3 MAS can be located in a blow tru mode or the stock mode before the turbo, i put the MAS as blow tru mode without the intercooler pipe blowing air from the turbo and the car rev just fine and the turbo spools like crazy, now what the hell is causing this problem? it looks like its not reading positive air pressure, is there any sensor on the intake manifold causing this problem. PLEASE HELP

Hey man I only live like 10 minutes from lancaster, give me a call in the morning and I'll check it out for you. I work on dsm's everyday. I'll send my cell number to your PM, or if your awake you can call me know qucik

maybe your map sensor could be bad..that happened to me when i had my gs..couldn't rev or pass 4000 rpm. turned out that my map sensor was dead..replaced it and boom..fixed the problem..but it might not be the map sensor..just something to look into..

 

[4g63knock]

its a new MAS from machV and it works my last test sure me all my conections are good, but there is something im overlooking or maybe my ECU+ needs tuning

 

[4g63knock]

MAP or do you mean MAS

 

[talontd92tsi]

did you ran that extra wire for the maf sensor to the ecu?

You never answered this question. I think it might be part (if not all) of the problem. The turbo cars plug for the MAS has another pin. Look into that.

 

[4g63knock]

this is how i set up the MAS, i cut the stock mas plug and use the 12v and ground for the gm3 MAS and the extra yellow wire coming from the gm3 MAS to the ecu+, this is how its supposed to be setup by the manual only 3 wires, wether the car is turbo or not

after multiples diagnostics, headches, nightbrakes and almost setcar on fire it all came out to 1 conclusion: WALMART PLASTIC BAG STOCK ON INTERCOOLER
