Hey everyone~

I just got done installing my PB ECU that i bought from a member here on the boards.

Now here's my delema.....I got the unit with just the unit, a R4 Engine Management CD, and the Stage 2 Map Cd, no extra tubing and no T-fitting for the vacuum line. So, i went to the local parts store picked up some tubing and a T-fiitting. Got back hooked up all wires and vacuum line. reconnected the battery and started the car.

Now, on the instructions sheet it said that you might notice a high Rev., but i had just the opposite. I had an extremely low rev., like 500 rpm. and after about 30 sec. the car died. So i repeatedly started the car again about 5 times and it did the same thing. i went and checked out all my wiring and everything is hooked up correctly. Does anyone have any idea what i did wrong, or how i can fix this?? i need HELP!! Thanks in advance

OH i don't know if this will help but here's my mod list:

RRM stage 1 turbo kit
walbro fuel pump
big bore fuel rail
vortech fmu
new RC injectors
stage 2 clutch

Please let me know with anything that you guys know!!

 

You might want to try reloading the stage 2 map again onto the piggy. Maybe it had a bad transfer... Why did the previous owner get rid of it? Is this a v.2 piggy, or an upgraded v.1?

 

there isn't a v.2 for a turbo application. also the vacume line gives it away. redo all of you connections.

 

I talked to a guy at RRM and he said the reason why the idle is so weak is because it's programmed for stage 2 application. I think the only other thing i really need is bigger injectors and then i'll be ok.

You guys got a suggestion for optimum injector size for stage 2?

 

u should have asked RRM. they'll tell you what their injector size are for their stage 2.

 

There is more than just map and injectors to Stage 2. Ther are other mods in order to make it idle properly but I guess you have everything so you know that. What size injectors do you have?
