Nistune Forums

Hello All,
I pulled the tune from my JWT and placed it into my Nistune ECU. Now a few questions arrose when i was looking at the software compared to the Hardware. First one that i saw was injector K constant read 328 And after doing the calculation from stock injectors of 270cc to my MSD injectors 50lb or 525ccthen my K- Constent would be in the range of 138. I tried that and the car wouldn't even start after i had resize the injectors. (put it back to what it was originally 328)The 2nd question is in the text for MAF it says its currently using J30_VG30DE-Late(500).....Now i know for a fact and verified the part numbers I am running a Z32 Maf. Does this make a difference in it. I am a big Hardware should match what the software is reading correct? So should I correct the items and try it again?

Stock S14 KA42DE injector K = 275 and after resize from 275cc to 525cc I get K = 134. This is with S14 KA24DE MAF so after doing MAF resize to J30 I then get K = 231.

Not sure how they got the K = 328 in that ROM image

Not sure why the JWT image you are using has a J30 VQMAP in it but that is what Nistune is detecting, even though you physically have identified a Z32 MAF. It looks through all the VQMAPS and matches it against what is in your ROM image. It found this one. Perhaps the calibration curve on these are close enough for them to work

Can you email me the image at all? I can check it out

Matt attached are the Bin file and a run file. Run file was at 10PSi. The MAF being used in the car is a Z32 verified by part number22680 30p00 A36-000 N62 and MSD 50lb injectors.
