Alright, I'm trying to figure out how I can correct this issue I am having, hopefully some AEM EMS pros can chime in on this.

The problem I am having right now is that the fuel map is mapped correctly for WOT @ specific loads. But, there are times when WOT and 40~60% part throttle is equivalent in load(which means they will use the same fuel map cell). However, it is running significantly richer compared to WOT @ same RPM&Load. I am guessing this is due to VTEC not engaged at part throttle <60% (this is where my VTEC engagement is set) or could it be somethinh else?. Now I'm thinking I have to use a VTEC fuel add while tuning the fuel cells for non-VTEC or create a throttle injection correction fuel trim table. VTEC fuel add worries me because there is no table and you can only specify a % across the whole RPM band. Is this going to scale properly all the way to redline based on the fuel map?

I am leaning towards the Fuel injection correction table but I'm wondering if this is the right direction.

Have anybody else ran into this problem?

 

No replies? That sucks. I'm having the same issue

 

Can you post your trim table(s)
