well ok so i just got my 84mm ls vtec setup running and everything is great except once i start the car after about 5 seconds the check engine light pops on and my wide band hits 10:1 - 11:1 .... and also when i jumper the jumper wires the engine light just shuts off and never flashes... what could possibly be causing this?

any help would be much appreciated

 

bump come on people i need to figure this out!

 

what wideaband and ems are you using?

hondata s300 and im using an aem uego wide band.. im also running a mustang throttle body and tps idk if that would matter at all.

 

come on someone has to have some idea of whats going on here loL!

 

Sounds like your ECU is going into limp mode. You have a ~4000 rev limit?

If so, check your soldering.

 

no sir revs up just great! its really odd if i go to check the code the light simply shuts off... the car isnt throwing a solid cel being i can put the car on acc and i have no codes at all but after the car runs for 5 seconds or so the light pops on and my a\f's drop out at idle..

and also i had this same setup running fine in a different car previously so i know the ecu is fine!

 

Soldering can go bad.

You checked the code?

 

yea i jumper the service wires and the light just shuts off and never flashes...

bump i am having same problem... also using hondata s300

 

Are both leds on the hondata unit green ?
If they are... Is your knock sensor enabled in your s300 calibration ?
If so, your ecu probably does not have a knock sensor...
Disable the knock sensor in the calibration & your problem will be solved.

If your still having problems, you really should consult with your hondata dealer.


Off topic but I am guessing you bought the hondata for some whored out price & contacted the dealer about the issue & received no response ?

If so, I have seen this happen several times on the board, you get what you pay for sometimes in product quality, customer service & technical knowledge.

 

no i had this exact same setup in a different car and never had a probleme.. ill check the lights on the ecu 2morrow and see if there both green!

 

BUMP

 

bump all the lights are green!

 

bump im gonna datalog it 2morrow..

 

well i figured it out once i started data logging. basically my brand new dist king dizzy is pure junk! throwing a cyp and now a ckp code.. ***** weak

 

dist wiring may be wrong. u went obd0 to obd1 right? double check the wiring at the dist plugs

 

Shouldnt you be able to read your cels right off the labtop (s300) and clear em?

 

yes u can and that is exactly what i did! i re-pinned a obd1 dizzy to obd2 plug and i double checked it the ckp is just bad! good ol dist king what a piece of ****!
