gsr prob

[DustinT2219]

OK i need you guys help my gsr is idling at 2500rpm but when i hit the throttle it boggs down. i also have a p28 hooked up to it so if you guys can help me please lmk

[marcos713]

is the p28 tuned to run on gsr specs? if not u have the wrong ecu. u need a p72 :goodjob:

[DustinT2219]

no its not tuned yet but do you think thats the prob

[marcos713]

yea mostly likely that would be it. the p28 comes off a SOHC unless its the 1 that came off a del sol. your swap is obd1 i assume right? if you have a friend that has a obd1 p72, try it on your car and see how if it helps.
is the gsr stock?

a p28 will run a gsr without causing that problem..he has other issues. check your tps

really? i didnt know that since the p28 is on sohc basemap..

i guess i should have asked if you had any CEL codes. if so, check em

[japan4racing]

it may not run it like a p72 does but it will run it fine...i ran one for a while on my gsr hatch.

oh ok thank how do i check it

[Batlground]

We can hook up the datalogger to your ecu and make sure its reading the tps signal. Or you can just test the tps input voltage to the ecu to make sure its working. We can also load the correct map on your chip for you if you are interested in getting that done.

[DustinT2219]

im interested but i cant drive it to you bc everytime the throttle is hit it boggs down and shut off i can pay someone some money if they can get it running or i have a whole punch of parts i can give away

[Batlground]

unplug the throttle position sensor plug and see how it drives.

[DustinT2219]

thanks alot that help out alot it still idle a little high but it doesnt bogg down when hitting the throttle

[DustinT2219]

if you unplugged tps and it ran better then tps/map is probably wired backward.
