Porsche 944 Turbo w/TransPro (Map)

[Rogue_Ant]

I have an 86 944 Turbo that I will be using my Translator Pro on, converting the VAF to MAP. I have not seen anyone use the Trans Pro for this application yet, and the current MAF/MAP alternatives don't interest me as much.

I will try to keep updated on my progress.

Excellent!

Ok, its taken a little while longer then expected... but time for an update. I've got the T-Pro installed and has been logging the stock AFM. This AFM should be somewhat universal for a lot of us Euro (Bosch) guys. I've also installed a 3" (Lindsey Racing) exhaust (no-cat), and upgraded the failing stock wastegate to a 50mm HKS-Style unit.








Now I'm ready to try to get it to work in Speed Density mode. But I'm not quite sure what to set my V Out1 to? Since the AFM is voltage based, I use V Out, but am not quite sure what to set it too?

I am trying to get the new MAF data into a beta version of the software this week.

I have some Nissan, toyota, and Mitsubishi stuff to put in also......

Yes, you should probably use V out 2, the gray wire.

Use V out 1 to feed a voltage to the ECU in place of the temperature signal from the VAF.

I will get back to you on the settings as soon as I can get the new data into the software.

Nice install BTW!!

Ok, installed a chip (http://gregorh.customer.netspace.net.au/motronic/) made for the Lindsey Racing Maf (common aftermarket AFM hotwire replacement). Finished wiring in the T-Pro. Using V Out1 to simulate the stock IAT (Mode 0, Setpoint 2.5v) and used V Out2 (Mode 11, Cobra MAF). I also used a lot of the settings that TurboBob posted for his 3KGT.
I then unplugged the stock AFM, left it in place for the moment...
Car started first try! Running a little rich at idle (944s like to run slightly rich @idle), but a little more then norm ~10.X AFR. But took it for a drive. Wow, I suddenly had throttle response! AFRs are cycling in the 14s like it was with the stock AFM. The car was completely drivable, even more so then stock. A couple of quick punches confirmed that the AFR tracking is working, this T-Pro just keeps getting better .

I will try to get a log up soon!

Extremely pleased!

WOW! Awsome job Rogue. We just had a 911 customer send us a MAF Senor that we flowed on the bench. Hopefully we will have some good software. Can you post or send us a copy of the connections you used?
Thanks,
Mike

I am not very familiar with the 911s. The 944 Turbos use two seperate ECUs (one for fuel/timing - DME, the other for knock - KLR). I opted to tap into the harness near the ECUs.

T-Pro Big connector pin #:
1 - WBO2
2 - WBO2
3 - KLR pin22
4 - Unused
5 - DME pin18
6 - DME pin22
7 - DME pin7
8 - DME pin21
9 - Unused
10- DME pin17

Here are the links to the DME and KLR connectors:

Hope that helps...?

Bob,

What info is needed for possibly having timing control? Also in the new version is the PT AFR tracking load based, like a 2D map?

Thanks

I need to know if the timing signals are 12 volts or 5 volts.

The PT tracking has throttle thresholds, RPM thresholds, and a MAP threshold.

It does not have a 2D MAP, and doesn't need one.....
