I can't figure out why my gsr won't rev past 3000 rpm in gear moving but in neutral can rev past 3000 rpm, I'm thinking its the timing but I really don't know I'm stumped somebody give me some advice thanks.

do you have a 2 step rev limiter intalled? If not your ecu could be bad.

danmej1

No I don't have a 2 step on it and it might be the ecu because the code came up but I took out the ecu and fuse and plugged back in after a minute then the code went away pretty if I do say so myself, please some more advice

Hmmm it wouldn't be timing (as far as being off a tooth or by the timing light). Is this a stock ecu, chipped or engine management installed? Are you knowlegdeable in how to test some of your sensors too? From experience i've seen MAP and TPS sensors cause this but thats just what I've seen personally. Let us know and we'll help you out

kinda ECU do you have, I have an ODBI P72, and a ODBII P72 sittin around somewhere.

danmej1

I have a obd1 p72 chipped by handcommand I'm thinking it can be the ecu but it might be that the timing belt is a couple teeth off too

danmej1

Don't you test the sensors with a volt-meter for the tps and map sensors or is their another way

00Red_SiR

I'm willing to bet it's your ecu.

You can test them with a voltmeter, but if your ecu/chip is bad, what would be the point of that? First you should get access to another KNOWN GOOD ecu (maybe borrow it from a friend) and then see if your problem persists. If it doesnt then there you go. I only spoke of the other sensors as possibilities but bad ecus cause all kinds of problems, including what you have there. As i said before, the timing being off has nothing to do with the car not revving past 3000 i can assure you that. Your car would feel as if it were severely underpowered and rev much slower than stock (too much retard) or knocking and underpowered (too much advance)

Think really hard about this... You think thats your problem but you just said that it does it in motion (which the ecu uses signals and feedback from other sensors) and not in neutral. Your timing at the teeth stays the same no matter what gear youre in or not. Now how would your timing being off have anything to do with not being able to rev in motion. Im with everyone else on the ecu.

A bad ecu has code 0 which does not blink. Some chips disable some codes too if you didnt know. As soon as you jump it the light wont light up. Is that the code you seen there?

lohatch

i had the chip pop out of mine before and the car ran but only at low RPM. or make sure the chip you are running isnt corrupt. did you recently change anything?? or get ahold of tony and i'm sure he will test the ECU for you. he is a good guy and takes pride in his work

danmej1

thanks guys I will get a hold of tony form handcommand and see if the chip came out of its place and it probably is the ecu because its always being moved from place to place, thanks for all the advice and the reason I couldn't get my response in any quicker because I just moved to another house and lohatch your from Minnesota is that how you know tony real well and is it a good idea to get my car tune up their at MAP or FullBlown, RSmotors, Dbperformance which of these tuning shops are more preferable to my accommodations for a gsr turbo e85 stock accept head studs, cometic head gasket all new gaskets around shooting for 300-350 please give me some advice here thanks

sounds like the ecu is in limp mode have u tried pulling the codes yet?

I think he's past that point. Earlier posts said there was a code and after resetting there is none at this point. Now he wants to know what tuner he can take the car to thats reputable according to lohatch.

angel_i

try replacing the dizzy w/ a know working one, and then try the ECU

danmej1

I'll try it out but I think the ecu is ok now no new codes and that's a good thing but I got to get the timing at tdc so I can get it running at it's peak performance and also does anybody recommend any tuning shops in MN, please let me know thanks. I know their is FullBlownMotorsports, DBPerformance, MAPerformance, RSmotors, and if anybody knows any better one's let me know I already tuned at FullBLownMotorsports but none of the other shops I tuned so people let me know please thanks

lohatch

go to jordan at MAP. tell him pat sent you and he will take care of you.

danmej1

thanks is he real good because everybody always said LJ from FullBlown is the best is that true but it is a opinion so I let him know pretty soon about to try to get everything right tomorrow thanks guys and have a happy new year

i think it could be the crank gear. samething happened to my friend's s2000 his crank gear was bad and would slip and causing it to go into limp mode..

danmej1

hmmm I wonder probably not but it could be
