No
I have Ford racing 47lbs
He has deka 60’s.
The tune I posted is the one I will be putting in there and I started from a fresh a9l2 and followed the steps entering his info.
Should I start with the latest revision ? I was just using the one I was on being that it worked very well.

Thanks in advance
Prob be after next week but I will give you an update.

Ok so if the tune I posted that from scratch with the proper data for deka 60’s tested flow of MAF and the error is still high what in the world.

I remember having a similar problem swapping mine from old scaled tune to new at the time a9l2 but can’t remember what I did. There was something to do with setting something to zero then entering proper info then changing back. maybe k constant?

What makes it so frustrating is I have a tune with old xdx etc working just fine only difference is MAF.


Thanks for the help

Ok Guys

I put his meter on my car and did nothing but log..After good and warm pretty identical to mine .998-1.008 error.

Whatcha think

the only thing I am questioning my self on is did I put in the correct values for the battery offset. The tune I posted is the one I did on my computer but the one I loaded is on his PC I can't verify until he is back in town.

Any other advice?

Thanks Guys

Yes
i had no problems entering the Pro-M meters info and dialing in maybe +/- 5% from published info. I may try his on my car and mine on his to see what i come up with. The motors are very close the biggest difference would be he has 3 step smaller pulley than i do.

Yeh. The thing that’s getting me is both cars have power pipe 85mm pmas housing and HPXE meter didn’t think it would be 30%
May just add to MAF and see if the error is consistent through curve

Edited ^^^

That’s what I am stumped by he ordered the HPXE and same housing. I even went back on my order to make sure there the same. The only way I have I have achieved a close to zero error idle is add 20% ish to MAF but that takes the top of MAF to 5000 and know that’s wrong


My HPXE was purchased before they were supposed bought out.

Also forgot to mention he said he blew it out with air compressor I am guessing that’s not good for it.

No at idle can’t get past that with new MAF

I have been using the A9l2 for a good while now and my car runs great! Now for the problem i am having. I am trying to help a friend with his foxbody
and he has almost the same engine setup as mine. It is tuned now with the old XDF before the auto scaler using a PRO-M meter it runs good but we have tried a few times to move to a new HPX-E meter because I have the exact meter in my car and he has plans of more boost and new 331 soon.

What happens is the fuel error goes to 1.30 pretty quick! I copied my tune and changed injector info over to the DEKA 60's (What he has) and check the differences and it states the MAF is over a 1000 off up top even after I copy a few times to make sure. I started from the A9l2 base file followed steps from website in order and copied MAF from my tune (separate instance of TP) and same thing MAF doesn't match. What's weird is when just do show compare data its very very close but when you choose show difference that's what is way off

I load the old tune with appropriate XDF/ADX etc. goes right back to 1.02 fuel error.

Am i doing something wrong or am I fighting a bad MAF?

Attached are the 2 tunes i have not gotten in to the other aspects yet just the main values.

Thanks for the help!!
