my laptop has been down so mind you i'm just using a scan tool for readings. during light cruising the INT's are right around 128 but the block learn reading seems to be a little lean (in the upper 30's). WOT is right on the money. should i continue to richen it up for part throttle or keep it where it is?
also, i don't see any tables to specify injector widths for an 89 tune so i have been bumping up the MAF tables to get it to richen up. car has responded well this way, but want to make sure i am going in the right direction.

Close on BLs is good enough.

Glad to see your doing the cal right, and editing the MAF stuff instead of mickey mousing things....

What are you judging this by? The BLMS and INT are locked at 128 when the ECU detects WOT

guess i can't say now that you said that. definately need to get the laptop up and running again to log some data. have been pulling spark plugs occasionally and they indicate a good mixture. pump shot feels strong and it pulls whenever i need it.

reading spark plugs is part of it. You also need a WB oxygen sensor to get your A/F ratio, and some dyno or track testing to gauge the performance differences from leaning/richening out the mixture.

I personnally don't have a WB yet(buying one when the car comes out this spring), so I have been using the voltage output of the stock O2 sensor. I have been told that keeping above 850 mv is safely rich versus below that starts getting a lean.

Just my .02 cents.
