It's not called ttp min, I believe Engine Cranking Injector Pulsewidth is the same thing.

That's uses temperatures, basically when you cold start the car etc.

Then your not meant to know it .

Basically that TTP Min, you will need to add a new XDF Item and fill it in with the information above.

Yeah duno how to do that haha

E480 is the RPM scale for the timing map. There is no TTP Min table in the B14 ECU.

There has to be, it Nissan wouldn't do it any other way. . But your right, I just double checked the values and what do you know, RPM scales where off. Double checking now, it looks like I made a typo when I was copying XDF items with Tuner Pro.

Check B14 address file.

#TTP MAX/MIN
TTP_MAX,&HE3A0,16,1,16,1,TTP MAX
TTP_MIN,&HE390,16,1,16,1,TTP MIN

Updated the XDF entry above with correct info.

Also they are side by side in the bin file when HEX editing.

E390 is an 8 byte table that has nothing to do with TTP MIN. As I said, there is no TTP MIN table in the B14.

That's a shame then, so how does it do it in that case?

I'm trying to get my 550cc's to be similar to the 370's. Even after tuning gas mileage plummeted a bit too much. I'm adjusting TTP Max too, hopefully that helps .

Eric, disable O2 feedback control and drive around and monitor your A/F. My K value is at 205, this got me 16ish A/F at idle, and 13-14 A/F at cruise, 12:1 at WOT.

I can't figure out how to get the cruise up, if I lower the K value then idle is at 17-18 and sputtering haha.
