    Dont.

    When you adjust the pressure you´ll make it to rich on top. Rather get it tuned to the ideal power output as found on the dyno. AFR hunting will only get you so far.

    you might have a point with that. but on the other hand, don't you think that the car is running kinda leanish until 5000rpm? i mean, values like 14 and even higher seem quite lean to me.. and i haven't even put a CAI on it. it's just the exhaust and the chip. wouldn't it run even more lean after i fit the CAI?

    oh, and one more thing.. the dyno graph was made with the oxygen disconnected. it's still d/c but i'm planning on fitting one soon as possible.

    yep, finally decided my mind. i'll leave the fpr as it is. i just realized that the pink injectors are rated 21lb@3.0 bar, and my fpr is already a 3.5 one. so need for extra pressure. cheers anyway for the replies!

    If you get it tuned like you really should all that will be sorted.

    It is leanish yes.

    i will probably get a custom soft for it this summer and fix whatever still needs to be fixed. cheers!

    edit: tomorrow i'll get the injectors fitted and i'll let you know if there's any noticeable difference in any way.

    right.. today i got the injectors and fitted them. at the first glance, nothing much changed.. the idle is a bit rougher, just a bit though. took it out for a spin, car definitely pick up quicker, especially in the mid-range revs. but still runs too rich, the exhaust turned to black and when the rev drop from revs into idle, the idle goes up and down a few times before it goes @650rpm. tomorrow i'll try do clean the ICV, which was a bit of a problem before fitting the injectors as well, but now it's got worse. i'll try and see if a CAI and cleaning the ICV will make any difference. so, to conclude, car feels faster and i think it really is a bit faster than before, but it definitely runs too rich and the idle has to be fixed.

    ICV cleaned, idle 90% fixed. it won't oscillate, but it's not 100% smooth, as it used to be. a bit rough, as i said. now i only have to buy and fit the lambda sensor, which i expect to be a pain in the back, but i'll have to do it anyway. that should definitely improve the AFR, as now i don't have a lambda sensor at all. finger crossed!

    p.s. does anyone know a tuning garage who in the luton area, who would be able to chip tune my car? ('93 e36 325i)

    Evolve is right in Luton and should be able to handle the tuning no problem
