hello everyone !
this is my first post because i am a new user of EFIlive . so here are some info: the truck is a hummer H2 , 8" custom lifted with 39.5x16.5 tall and wide tires. on the engine there is a 218/224 0.550 with 112 LSA cam , ported and polished heads with 11.6:1 comp ratio , longtube headers without cats , straight side exhausts , custom air intake through the hood with the MAF bolted 6" near the intake throtle...i had an handheld programmer but i have decided it's time to go and get a real tuning device
so i have read pretty much on this forum and followed all the instructions with the autove tuning, but i think that something isn't right regarding the maf. i have a 5 wire maf with the iat included and seems that despite i have altered the maf frequency fail readings c2901 c2903 c2904 and c2906 i am still able to see the maf frequency on logging ? is this normal ? how does the ECU thinks in this situation ? he is able to see it but doesn't calculated it ? am i going in SD mode ? and if i try to disconect the MAF , it is going very lean and can't drive in this condition ! please see the log files and give me some advice !
after that i have decided to leave the MAF connected and go for autoVE log test drive. it was a 5 min drive and did get a main VE table , but it doesn't look very different than the stock one. i had to smooth it a little bit because of some spikes i've got , but anyway if you look at it you can see ...please again i need some advise if i have done everything correct and your opinion !
base.tun is my "stock" tune
ve0000.tun is after receiving the ve table from the log0000.efi
please look at the difference between the main VE table !
base autoVE.tun is the calibration i am using for autoVE
please look also to see if i have set it correct !
thanks for looking at my post and please let me know what do you think ...
PS: i am using here 95 octane pump gas , my tune file is a little modified from stock for idle , some rear o2 sensor , p1514 that i am receiving i think because of the cam and the actual MAF position...etc...
