lean misfire

Post by Fordy »

hi guys ive got a problem i think somewhere down the line my ttp width max has been changed to standard :(

i did have a horsham stage 2 chip before that i downloaded and put onto my nistune for awhile now i've had a lean stop coming onto boost at 3k and can be driven through it

tried everything so far apartfrom ttp max,

im running nismo 555's and would like to know what ttp max settings i should be using as these are mine at the moment


should i change the ttp max to 255 or leave it as it is?

TTPMax is a limit on the maximum injector opening size

If you dont want the limit in a particular area you can either increase it furhter or just max it out (255)

Probably from about 2800 onwards put 255s in the columns to max it out and see if you get that lean patch still. Nistune automatically fills to 255 during injector resizes for this reason

all fixed now :D

i got the stock bin and resized the injectors then copyed the ttp max over to my current map and it drives lovely now just a bit to much fuel where i tried to map the problem out but it works again :D
