Does anyone have any experience with this ECU.Please post pros and cons......Thanks....

 

Great ECU, but it needs to be tuned. I went from 275 miles per tank down to 175. Thats on a stock JDM b16 w/ I/H/E.. My car runs much richer, but needs to be tuned..

 

gas mileage will suck because it does not run in closed loop, meaning it doesnt
read the O2 sensor and change a/f mixture. otherwise it runs rich and has
aggressive timing.

 

Steve, let's dyno my car before ...., running my present Mugen set up for a before/after kind of thing. Ed

 

So what ECU would you recomend that doesn't completley kill gas mileage???

 

One of ours.

good lord!!

 

i gained 10whp and 7lbs of torque to the wheel through out the whole power band....thats on a I/H/E B16A

 

Lots of fun untill you go boom. I dont think its a good idea to run the chips. You have to keep a very watchful eye on your car. These ecus cause more motors to fail, mostly I think from no knock retard, and also from extreme timing issues.

 

I am running the mugen chip that i got from eg6ajk. The cars feels so much stronger in vtec. I havent dynoed my car, but gas mileage did go down a bit. I leaned the car out at narrow throttle and it seemed to give better mileage.

 

yea the mugen chip is good but kill gas mileage i notice that and i notice that my vtec kick in hard and man it give alot of fuel and im thinkin im runnin rich rite now but i like it though it a good chip

 

hey if i had a jumper put in wiht the ecu, can i just take out the ecu and run the stock ecu fine, its a chipped p28 on a gsr motor, will the stock p28 run find for just daily driving?

 

You can use it. But there are a few problems with it:

1. 4800RPM VTEC point. This is simply too low for a B16A and will actually cause a loss of power as well as fuel economy. Furthermore, if you are running the motor with a JDM S1/J1 transmission, this will put VTEC switchover at 80MPH. This is not good for freeway cruising. You DON'T want to spend hours on end in VTEC. Nor do you want to constantly be switching in and out of VTEC if your speed happens to fluctuate slightly above and below 80MPH.

2. Fuel maps probably too lean. I am not sure how big a problem this could be for daily driving on a basically stock engine.

3. No knock sensor protection.

4. 7500RPM rev limit hurts power output.
