I posted this under another post w/ little results, so here it is again...

I recently installed hondata w/ a P06 ecu in my LS. When I run the car the tach goes wacky at 5500. I dont know if its only at WOT, its hard to get that high at partial throttle.

Anyway, it started exactly when hondata was installed. My tuner has no idea, and Hondata says its a bad coincidence and its a probably a problem w/ my dizzy or ignitor, but i doubt it. Also, I found another guy w/ a LS on the Hondata forum that had the same problem, but never fixed it. Leading me to think it is related to Hondata.


Any thoughts.

 

its most likely your timing or fuel curve that needs to be adjusted

 

what would that have to do w/ my tach?

 

Nevermind, i thought the car was hesitating or seomthing, once you explained it on PM, it sounds like its purely electrical BS. weird.

Hopefully someone else will shed some light on this.

Whats the deal people!
My boy has a 2000 GSR and we bought obd2 to obd1 plugs and p28 Chipped and now when we rev his car starts good and then right after 5000 it drops right down to 0 and then catches up again to where ever the RPM Are suppose to be, I check the ECU and The plugs on different Car and it doesnt do it, Changed just the computer and still does it but it doesnt do it with the Factory Computer.

 

damn i hope i dont have this problem with my hondata when it's installed, bump-help this guy out

 

I had the same problem. Car would run like normal, but the RPM needle would go all over the place. I changed the ignitor (i think that's what u call it in english) inside of the distributor and its all okay now.

 

any idea why it happens at EXACTLY 5500 every time?

 

Where did you get your ecus and adapters?
