i dont understand 1 WORD YOU SAID.

FLIPboi

(TRANSLATION) --is it ok to run my integra Ls motor with a civic Dx ECU, or will it mess up my fuel mixture , beacuse with my Dx ECU my Ls motor runs better, so is it ok to run it like this???-how is that can you read it now can you help me out ?, i was tring to type quick short ebonic hand

Kamin

define "runs better"
and what year car, what year motor ?

FLIPboi

deffintion of better -- dosent lack power on accleration , and idles normal, but with the ls ecu it ran like crap man 93 ls integra -in a 96 civic dx

b20guy

I thought 99 ECU's had different plugs at the ECU than 96-98???? What is the number on the side of the ECU? xxxxxxxxx-xxx-xxxxxxx

Flipboi,
It is ok to run the dx ecu. Actually it is probably better. Honda computers are programmed to run rich at WOT(which is safer, but can also hurt power slightly), so when you run a computer that it is programmed for a sohc, on a dohc motor, the extra air that the dohc flows will lean the mixture out slightly and provide a stoich mixture. I don't understand why you are having idling issues with the other computer however. Did you throw any codes with it? Did you throw any with the sohc? If you want some good hard facts on running the sohc computer go to the hybrid-honda webpage. The performed a whle bunch of dyno tests on a b20 with a range of computers. I think it is something like http://www.hybrid-honda perf.org or something like that. Just do a search for Hybrid Honda.

if i were you i'd try an obd1 LS ecu..a 94-95 one.

FLIPboi

im throwing the same CEL codes with both of the ECU but i juss if it rus better then i prob. keep my dx ecu on . and for supercivic , i porb will try that but then i would have to get a obd 2 to obd 1 jummper harness and a ecu and im kinnda on a bugit, but ill keep it in my mind if i run it to more problems , thanx guys

Kamin

is the ls ecu OBDII?

Taken from hybrid...

FLIPboi
