im hitting the rev limiter at 3800 on my new ecu. limp mode
 

I just got my built zc and turbo kit together then got my ecu chipped. now im hitting rev limiter at 3800 inevery gear. im only throwing a code #6, and thats an easy fix. but wil this cause me to go into limp mode? other than the rev limiting the car runs great. The guy that chiped it put the launch control at 3800 but said that he set the top limiter at 7200 so what is causing the low limiter? if you have any ideas let me know thanks, Jay

Code six is your coolant temp. I don't beleive that should throw you into limp mode. How's your VSS? is it working properly?

Whats VSS?

Re: im hitting the rev limiter at 3800 on my new ecu. limp mode
 

speed sensor

Re: im hitting the rev limiter at 3800 on my new ecu. limp mode
 

would the speed sensor cause it to go into limp mode or rev limit early like that?

Re: im hitting the rev limiter at 3800 on my new ecu. limp mode
 

Yes. if its reading wrong. I think you should look esle where though.

if this is in a crx it doesnt have a VSS it runs with a cable. so thats kinda out of the question. last time my zc did that back in the day it was my crank angle sensor

Re: im hitting the rev limiter at 3800 on my new ecu. limp mode
 

is your car vtec or non and what kinda of ecu are you running

Re: im hitting the rev limiter at 3800 on my new ecu. limp mode
 

its a dohc non vtec zc with a pm6 ecu. wouldnt the crank angle sensor throw a code if there was something wrong with it? Anymore ideas?

Try turning off launch control. It could very well be your VSS (which is present in the crx).

Re: im hitting the rev limiter at 3800 on my new ecu. limp mode
 

yup, on the back of the guage cluster with the cable driven speedo's is where the VSS is. The ecu still uses that information as a refference and if something is not right, the ecu will normally throw a code 17 (VSS) for it and your launch control etc. can be screwy. It could be a number of things but that was one that came to mind.

if ur vss is bad it will.... 1. throw the code and 2. only rev to 3800 which is the launch control. the launch control is set to turn off at a certain speed. if it doesn't kno how fast your going then bam.... ur stuck at 3800. fix ur vss and ur good to go.

Re: im hitting the rev limiter at 3800 on my new ecu. limp mode
 

hahaha, I thought that code 17 was electrical overload

I knew my VSS cable was snapped but didnt think anything bad would happen of it other than not knowing my speed

And I blew my motor anyways... ----

replace or check your crank angle sensors and the wiring all the way back to the ecu had the same fu*king problem got in fixed at a local shop good luck! O0
