Hi!

I have some problems with my AFR, when the injectors pulsewidths drop down at about 3200 rpm my AFR are too lean (13.5 - 14) at about 0.7 bars of turbo pressure...
I try to raise the TTP max to 12ms but it's not the problem (I think)...

Help...

Just an other thing... I think that in the S13_CA18_128_E.adr in the last pack =>

the TTP min and TTP max are inverted?

TTP MIN/MAX in previous were the wrong way around. This got swapped around the latest ROM image pack

What's your TTP max with 550cc injectors ?

with the 550cc I had 15ms in TTPmax after 3000rpm with no problem.

I think your problem is not there, I have exactly the same graph as you , but I have no AFR problem at all.

injection time drops when turbo come on boost, at 3600rpm for my GT2871R .
