I struggle to understand why they do it though, as the MAF is the finest piece of engineering to tell the computer what load the engine it is at. I guess that is why turbo charged Porches do it that way (as explained to me by an ex-works Porsche tuner/mechanic).
That said - all my engine dyno work with the MoTeC the other week was MAP based, but there is a reason for that. Not a factory computer, Traction Control module, or ABS or AntiTheft module etc. in sight! Unless I ran a big long loom out to the car and spun the wheels with something!! LOL.
Cheers,
Hymee.

I'm happy to do some more tests and make them public, but I did some tests a couple of years (3+?) ago where I hooked up a combination pressure/vacuum pump to the Baro. I can't remember seing the OBDII PIDs for baro going that high, as I think their range is less - but I need to check the OBDII J1979 specs again. There is also the calibration curve available in the PCM. The trick is to do stuff outside the "normal" atmospheric BARO conditions.

Hymee.

Hi Andrew. Already done that and sent it to Jeff. Now the Cobb people need to include support for it a firmware update. I hope it happens soon, it's very frustrating that it's sitting here and I can't do anything with it.
Add to that that I have an intermittent CEL and it would be really useful to be able to read that when it appears.

Dear all,
I would like to publicly apologise for breaking a rule. I was aware of the "private vendors rule" and abide by that, but I was not aware of the other catch all rule 8. Also, I'm not sure if I am a vendor or not, as I don't have a vendors area or advertising banners etc. Anyway, I'm sorry, and I hope no harm has been done to the community.
Jeff, do I have permission to post in your thread? I feel that 98% of what I have posted had nothing to do with my products, and was genuinely related to the topics at hand (especially the MAF/MAP stuff).
I hope I get permission, otherwise my apology will get deleted LOL.
Cheers,
Happy Hymee, not grumpy Hymee.

If I wanted an AP to tweak a few things like OMP flow, kill codes for exhaust, improve fan settings, would it play nicely with my Int-X which is handling my fuel management? Would I need to uninstall my Int-X prior to installing the AP so it doesnt interfere with the reprogramming of the ECU and can then reinstall Int-X after?
Or is the whole thing completely out of the question and they cannot be used in conjunction at all? Couple people have speculated to me, but I figure straight from the expert is the best bet.

Kinda a waste since the AP can do it ALL, but that is up to you.

I have my Microtec installed at the moment (waiting for a base calibration from Jeff) and the AP wont even install with it in between. I haven't disconnected it yetto see if thats definately the case but I am pretty sure. Will be checking this tonight.

I doubt the AP would play nice with a piggy back unit. Even still, the AP will handle all the functions you need.
