MAFT???? MAFT tuning ???????
I've been toying with Getting my car tuned with my new TR ported MAF ends and MAFT and this is where I am. I have the MAFT base setting at 10% rich and the WOT setting at 6% rich. LTtrimsB1 and B2 fuel trim cells 0 - 17 never get above 3.1% at cruising speeds with the exception of acceleration. There is no pinging at WOT and my 02's hover around .88 - .90. There is a slight bit of knock retard but it never goes over 2 degrees and is not constant throughtout the RPM's so I think it may be false knock. Today it wasn't very HOT so I don't know how it will respond in extreme heat. My questions are as follows:
1. Do those LTtrims at cruising speeds look good? Like I stated above they don't get any higher than 3.1% but seldom go negative while cruising.
2. Is there an acceptable amount of KR or should it be 0 degrees at all times?
Any suggestions would be appreciated.... I'd like to get my tune straightened out ASAP. I feel like I'm beating the **** out of my car doing WOT runs trying to get this right.

Re: MAFT???? U need to concentrate on the BASE setting ! <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />
I would not even use the WOT unless U are on a dyno with some wideband capabilities ! <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
I tuned my car with the MAF-T on the dyno and then A-TAPPED to check readings against my dyno charts !
U also need to make A adjustment at a time on the BASE and put 50 or more miles on the car for the PCM to learn that adjustment THEN A-TAP it ! <img border="0" alt="[judgement]" title="" src="graemlins/gr_judge.gif" />

Re: MAFT???? Thanks for your help guys. Do you guys think I should start from scratch or just put some miles on it at BASE 15% rich and WOT 6% rich and ATAP it again? I think the 01 - 02 cars came a little lean from the factory. At times I got pinging with just the MAF screen removed but not very often. I would like to join you guys at the DYNO day at Mike Dez racing on the 15th. But I have a graduation party to go to that afternoon <img border="0" title="" alt="[Sad]" src="gr_sad.gif" /> . Hopefully I will be making it to the track Saturday for Camaro heaven day.

Re: MAFT???? Personally I would just turn WOT back to zero and leave BASE AT THE 15% setting then drive it for 50 or more miles then A-TAP and see what's going on ! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: MAFT???? Cool that's actually what I'm thinking. I'll move the WOT switch tonight and ATAP it again in a couple of days. I will avoid WOT runs until the next ATAP session. I'm running ATAP on a P166 with 16MB of RAM. I seem to get a lot of errors with the Windows version. Anyone prefer the DOS version.

Re: MAFT???? I would recommend 15% rich base,0% WOT to start off.The MA ends are killing you.The 01+02 cars do not like the MA ends.
You should shoot for around -5%-0% cruise and 0% WOT on the L-terms.You should see the 02's around .90-.93 at WOT with this setting.Then you can lean out the WOT till you end up with a .89-.90 consistantly and 0 KR.
Do you have HPP3 tuning installed?If so get rid of the power programming.
