getting bummed...help somethings wrong

[blksn955.o]

Yes, I plan on doing it this winter while its cold out.

I had just pulled the intake back in april and wanted to get some driving time to break it in. I have a set of 1.7rr awaiting to go on.

I need to do another driving loop in the next day or so and see if the j4j1 maf transfer feels any diff, than no tweecer I realy hope so... I will be dataloging this for sure.

it started raining just as I left so I realy couldnt drive much.

Is it possible for the connection at the j3 to be partial? I mean I find it very, very wierd that the drivability sucks but power is gained with the tweecer off, and that the only thing the tweecer does is give me some drivability with much much softer perf. even with timing and fuel made better.

OK



btw...what is the most airflow you have seen in your dlogs?

I datalog the MAFV for the EA program, and I see 4.53621 @ 5135.5 (the highest I reved it to on the datalog wot, due to traffic). EA sug. a new MAF curve and from my datalogs there is a dip in the mid range of the curve not much but there is one below 2.8v (the only part that does not follow the exact same j4j1 part of the curve) and just above 2.3v. I wouldnt think this would make it soo soft perf. wise at the track??? were else should I look at in the tune?

I also made a T4M0 5spd gt tune and am going to see if there is a noticable diff. I need to get to a dyno...this sucks.

WOW ... 4.5 maf volts ... not a lotta room left in the old maf curve.

What about your airflow?
How many kg/hr do you see in your maf column at max wot rpm?

I know about getting to the dyno frustration

Ever since the little woman lost her good paying job, I've had to really cut back on playing with the Stang

wouldnt that be .4639 volts left as its on a 5v scale? A local guy has a 80mm 99 lightning maf for sale for like 65$. I have been looking real hard at that.....

I have no idea with the kg/hr are I have never logged that, let me do another log tomarrow (later today actually) and see.

just in case here is a thread I started on the eectuning forums.

I am off again tues. and if the weather is nice I am going to try and get back to the track.
