i did gsr swap in my ek and used a Si engine harness. i also used the Si ecu.
i took it for a test drive and it doesn't have any low end. i was wondering could this be the ecu or the timing???? it doesn't seem like its running right...
somebody help please......

 

I am not a "dr. honda" but it sounds like timing to me check that it is in time cause it sounds like it is barely out of time. That is just my suggestion hope it helped. Oh and the doctor i normally consult when i have problems is Dr. Haynes.

 

did u wire up the secondary butterflies?

mike

 

i got the skunk2 manifold

 

And your ecu is chipped yes?

 

did you set the timing? I had changed my wifes dizzy on her car and that had messed up the timing making if REALLY slugish... i set the timing with a light and that fixed it...

 

ecu is not chipped

 

Well I think that would be the prob. Contact kenji on h-t he will set you up.

Also he would verify if this is the problem or not.

 

anybody else gotr any suggestions

 

so it is probably the timing...anybody else have this problem?????

 

Your running lean...and possibly the ecu is retarding the timing due to knock.

I ran an Si ecu for alomost a year and when I went to the dyno....I was wayyy lean. Bump the fuel, tuned the cam gears...went from 163 to 175 and +20ft lbs in the mid range with imporved throttle response everywhere in the power band.

Timing was set at 12 Bumped it to 17....gains from idle all the way up

VAFC/ FPR used....VTEC lowered to 4900 gained more mid-range...

Tuning that motor will reveal the culprit.....if nothing else youll be able to make more power with tuning and fix the "no low end" problem

 

Get ECU chipped, and fix IAB's to work properly.
If IAB's are open all the time, big lag off the line.
