Fuel map problem with last version

Post by Garrett_si »

Saturday I had to tune a S2000 2001 comptech supercharged

750 cc injectors
255 lph fuel pump
Hondata s2000 kpro
watercooled system

I resized the injectors, and want to adjust the fuel map tables, it has no effect

I made an overall fuel trim to adjust it, the part throttle and idle were correct

but when at WOT the 4000-6000 rpm power band was lean, I tried a lot of adjustement in the fuel map, without any effect

I erase the ECU 2 times, and rewrite

I use an old version 1.3.7.0, and I was able to tune the car completly

I attach the cal, and the datalog when it was lean. the wideband used is a PLX M200 wiring to the ELD pin

the car is fully tuned, and everything is fine for me, but the last version don't work on this car

You have lower values in the high cam than you do the low cam at your vtec transition.
