Thanks it's much better.

Thank's, it's much better now. Question. I have both CABHO and CZJAL on the chip, I noticed that the CZAJL shows approx 10% more RPM thru the datalink on my old Snap On 2500 scanner, something to do with PIP settings? I checked it several times to be sure. Doing an EDIS conversion on my 89 gt with that strategy and ecm and wonder if that's going to be an issue on it.

thats your strap on scanner thats giving you bad data

no why would it pose a problem?

Silly me, I was thinking EEC V tach output, not direct to coil for tachometer sense
