I've self tuned my h22a on crome. Car runs absolutly amazing except the fact that at around 4000 rpm (vtec set engagement) if I'm cruizing at around that 4000 RPM (+/- 100 Rpm) it feels like vtec is trying to engage/disengage repeatidly.

I've never owned a vtec motor so I don't know if thats normal?! (even with a stock ecu?)

So my question is, should I adjust how far apart the low/high load Vtec Engagement/Disengagement Rpm are to stop that fluctuation transistion if thats what that issue is even? Right now the engagement for both high and low load is set at 4000 and the disengagement is set at 3909 or around that.

Also, my second question is in regards to the injector battery offset. I have an advanced table that I never adjusted but the number in those tables all accross are like 16,000 something. What the heck does that represent?

Any help would be appreciated.

 

If you set the low load engagement to a higher RPM it won't come on at light cruise until the RPM you specify.

Can't help you with the second one. Sounds like it's incorrectly represented.

 

AHh, hey thats a good idea. So it won't engage unless I'm at a higher throttle?

What throttle posistion does low load to high load change?

What exactly does battery injector offset do than?
