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.

 

To my knowledge ProM does not provide the the transfer function or flow data for the meters they sell. But I think Avos has done some work with them a long while ago in the creation of the Jaguar calibration for their meter so he might have something.

I had the same experience. Eventually I gave up, trashed their part and used a programmable meter to create my own.

 

They do. Their website has option to order a new i bust need flow cur e to be dow loaded to tve aftermarket ECU.

 

Fascinating.

I did not get one of those with the meter I bought from them and it sure didn’t work worth a damn with my 4.2L.

 

Here is one from a 3.5" MAF from Prom, just can't remember if its for the AJ27 or AJ34, it was for the stock injectors

Is the intend to use the MAF unit on your car?

This is what I have, for AJ27 ProM92
I've not fully validated that it is good enough, although so far so good, except at the low flow end where it seems slightly off unless I have a vacuum leak (don't think so, but have not fully dug into it....) - I tweaked the curve with Arduino/DAC, but have since removed and reinstalled the intake elbow which could have been source of leak, and not yet re-checked the trims.....
