I need flow data sheet for ProM92 MAF for stock 4.0 injectors. When I bought it many years ago I never got the data sheet. ProM has poor customer
service without response for phone calls or emails. If you have such a tune data sheet for 4.0, please PM me. Thanks.

 

May want to ask WaterDragon... https://www.jaguarforums.com/forum/x...n-80-a-102383/

I know your looking for a more direct answer, but found a few other older threads and at least one your in... https://www.jaguarforums.com/forum/s...rchid=12910968

 

I already sent PM to WD. We talked a lot years ago when WD was active here....very power hungry guy If I do not get the data sheet, then we jsut to make flow test here - even we can run with MAP like we do now.

 

Someone whom you might want to work with on this may be Count Iblis. I know he wants to go with a TVS 2300 SC and that will require more flow. He was on the design team also and has designed and built his own solution to the weak 14HU diff. Big Mopar guy, ...pretty mellow.

 

Well, the car is 99% ready 5min ago I tired to call ProM once more and finally someone answered. They do not have database for the MAFs they have sent out if customer has lost the orginal flow data paper ( I have never seen it ). The only way is to send the MAF back to them and that's stupid idea to do from here. No problem, we flow it here.

 

Thanks for the vote of confidence Highhorse.

Im a little way away from using a Pro-M- I will no doubt be doing it in the future.I AM looking into he 2300, but I have a lot of other things on, so my be a few years away...

This week I will put on the bored out throttle but I'm still on the 4th gen M112.

The 2300 will take some time, I also bought yet another car, (a Mercedes 560SL- for DIRT cheap- excellent condition) and am focusing on getting that sorted.

XJR-99 if you are able to get through to them and harvest the correct info-I'd be interested in learning more. Where are they based?

Do you want me to contact them on your behalf?

 

I'm keeping an eye on this thread also, I just reached out to ProM to see what is needed to calibrate a sensor to a 2000 XKR with a 3.5 in intake. Fabricating and installing I can do, calibrating and programing are beyond me!

 

You can see a couple datas I was looking for here: https://www.jaguarforums.com/forum/x...-4-0-a-222528/

Back in 2014 when i run the old engine with TS I ordered ProM92 with tune for 4.0with OEM fuel injectors ( the orginal tune was managed by some seniro forum members , ie Avos etc. ) . Then i broke the engine and the new stoker engine came with much larger fuel injectors - so it was not possible to use that MAF tune - without sending it back to ProM for re-tuning. When the new engine was finally ready I got Abaco 85mm MAF. Abacos you can tune yourself. Unfortunately Abaco stopped their businsses and you can not find new Avaco MAFs anymore. It was very difficult or actually impossible to find right tune which worked well withbig injectors and AJ26S ECU ( this can be AJ26 ECU based or some other reasons we found later ) Now we are not anymore stuck with closed Denso enviroment and can use MAP or MAF. My engine guy prefers MAF because for steet engine it gives best data of incoming air flow. We have now 92mm TB and 102mm intake tube ( 4" ) with inner diameter of 98mm. 92mm MAF is good sized for the current set-up. Of course we could use the smaller Abacos we have two pieces.

I finally got conact to ProM. They said that they do not have any database for the MAFs they have tuned and sent out ( even i had my order number etc ). Since I never got the flow data sheet with my MAF, the only way to know the 37 point flow data is to send the MAF and big cone filter back to ProM. Yes, they want the filter also. That's not reliable from here. We can do it here. Looks like they really make tunes individually, so it's too risky just to copy the data from another MAF for same engine / injectors.

 

ProM had the full intake and also different MAF sensors for doing the base line measurements, both for the AJ27 s the AJ34)

The tune for the stock injectors (which you have) will not allow you to go to your targets, as you will be hitting the 5 volt barrier quickly.

Best is to ask ProM for a re-tune, based on bigger injectors to get you in the better range for your targets.

As you have your own ECU, you will have a base to start from, and fine tune it on a dyno.

 

All those MAF tunes are based on faking the signal for the ECU to get the wanted range. The tune you sent reach 5V at 460g/s and the antoher posted one for AJ27 a bit higher. The real air flow through the MAF is much bigger. MS3 Pro Ultimate has tools to scale the flow to the wanted level. We just need the curve.

 

The MAF you have now is scaled down, and then you want to scale up again these values. Maybe hairsplitting, but you lose granularity in that process.

What puzzles me is why you are not able to use the base you have now, you have a curve to start with, which you need to finetune to your ecu. in simple terms Its just matching a voltage of the MAF to injector opening time that you need, which you have to do on a dyno, then you’re set.

I acknowledge I don't have experience with the ECU you use, but the principles in software remains somewhat the same imo, so where are we misaligned?

 

If you still have it, and its operational and you are willing to sell it, I would be interested in buying your Abacos MAF and accompanying data/calibration.

Its probably big enough for what I have planned.

Let me know

 

For just in case you want to sell the ProM-92, I may be interested as well pending price.
