Is the different % on the verticals the % of throttle for part throttle maps?

No ALDL available. Direct scan / cell tracing _should_ be out shortly, with the next version of TunerPro (the TunerPro author is a little behind schedule). And when it is publically available, I'll make sure to update the files necessary to support it.

IMO, this type of stuff should have been done long ago for the 951...

The DME never knows throttle %. It only knows if at idle, part-throttle, or 'WOT' (which is trigger via the KLR).

An ALDL requires a datastream from the DME. The DME is able to output a serial data stream; unfortunately, this ability is disabled in the factory coding. Something I'm looking into - just need more days in the week!

AFAIK, only one company, VR, has a true MAF chip, meaning they have done the work to disassemble the factory code, then change the transfer function portion and get a working result (putting it simply).

I'm not sure quite what you mean, perhaps something is getting lost in translation...?

I can't find the thread about it, but Russel is talking about a true MAF chip. Yes I know VR has a very good MAF chip

Lost in translation - meaning I was not sure what you meant.
I have not heard anything about Russel making a true MAF chip.

Seems to be a bit of confusion here as to what my MAF chips do, or don't do. When someone orders a chip for a MAF and they have a piggyback in place then the chip they get is an AFM chip tweaked for the MAF's behavior.
When Dave Lindsey and I started working on a MAF chip, he installed two of his MAF meters of different calibration on his car in front of the AFM. The AFM was running the car, the two meters were being logged. From that data, I modified the AFM transfer function in the chip to read the MAF signal directly and perform correctly. This chip was designed for a specific MAF, and will not work with another unit of different calibration. Dave's car blew a turbo during our testing, and that has absolutely nothing to do with the chip. The center shaft blew right out the exhaust pipe. So to say that ONLY Vitesse, APE, and Hally have created MAF chips is simply not true. And once again, the people on this thread saying this have never used my products and I would really prefer they limit their comments to facts they have first hand experience with.
Dave and Mike Lindsey have spent more hours than either of them can count supporting people even if they have an obscure configuration, and some not even using their products. I strongly feel their support is second to none, including my own. But that's not for lack of interest or caring on my part, my life has changed drastically since I started doing this stuff. My family is split apart, one of my biggest computer consulting clients went out of business. I travel from MA to NY often to see my 5yr old son, and the rest of the time I'm trying to make a life here. I sunk over 20K of my own money into development of chips and kits for the 3.2L 911 community. Not one has sold. So now I'm selling the 911 and moving on to the 928 and 968. I have told people some of this, and that my availability might not always be optimal. I apologize for this, but life happens. I'm not going anywhere, I'll always be here, I'll always be developing new products, and I will always do my best to support them.
Rich, good luck with the new chip and overall project.
Regards,
Russell

So load (air flow per rpm) would be taking into account boost signal?
