Long term ft

[Manny Alberto]

Hey guys so i just installed a 3.5 intake on my mazdaspeed. My concern is after I tuned it my long term ft is at 20.31 on idle but when i gas it it goes down to -9 to -11. Can anyone tell me what is going on? Leaks?

Did you get a tune when you did this or did you just toss it on the car and hope for the best? You need a MAF CAL to run a larger intake.

Yes i did from Will (pd). Im hoping i may just need another maf calibration because the car is idling rough.

Check your installation for leaks. MAF cal should be pretty close first pass

You should post this in the troubleshooting section. Your LTFT at idle is indicating a leak somewhere past your MAF. What are your STFTs?

you need like 50km for trims to settle dude, have you gotten the maf cal back yet or is it just base map? any other work at the time? check for leaks with a boost leak test

Thanks for replies but my ltft settled down after doing a leak test and getting my 2nd revision now its sitting at -+ 3.91 on wot and about 5.7 on idle idk if this is still normal but i guess will didnt seem to mind it when i sent him my datalogs
