Re: Air Fuel Ratio maps 1,2 and 3

FIX: my car was running off the table, i.e. the fuel table went to 9,000 rpms but i was revving to 9,300. i had to rescale the fuel table axes to allow myself to enter a a value for the highest rev range. that allowed me to lean out the 9.000-9,300 range.

Re: Can't get 2,000-3,000 rpm range to enrichen!

Also, all three of the charts below are with the same tune, yet the AFRs between 2,000-5,500 seem to be very inconsistent in terms of enrichment. it honestly looks like sometimes the ECU is trying to target 0.95 lambda, and other times it suddenly drops to the values more consistent with my AFR tabl...

Can't get 2,000-3,000 rpm range to enrichen!

My AFRs from 3,000-9,3000 rpms are looking decent, but i keep trying to enrichen the AFR tables in the 2,000-3,000 but it seems to have no effect. any hints on richening up the 2,000-3,000 rpm range? I'd like to see 13.3 AFR / 0.90 lambda.

Re: Air Fuel Ratio maps 1,2 and 3

I have run into a challenge where the car is running a tad too rich at 9000 rpms (see attached data log) but i am approaching the adjustments limits of the fueling table. My excel calculations are telling me i need to enter a fueling correction of greater than 1.0. Question is, can i lean out the ca...

Re: air/fuel incorrect

Looks super rich. Are you able to edit your tune and lean out?

Any point in adjusting load limits?

I was wondering if, for an NA application with minor bolt ons, whether there's any point in messing with the load limits? What effect does increasing above 1.0 have?
