Yes I am trying to get it down near 12 because that's where it was at when I first got it from Brad at George's imports. I've talked to Brad a couple of times and that is my first choice he's just about 3 hours away. And now I understand there are some issues going on with Brad that may postpone me being able to take it up there. But from the conversation I've had with Brad it is in complete control of the fuel map and the ignition map I think it still uses part of the Saab ECU but I don't know in what capacity. I spent most of the day yesterday and I've got it really really close to being dialed in. I do still have a throttle position sensor. Brad put a new one on 8,000 mi ago maybe it's out of calibration maybe I'll check that tomorrow. The split second computer hooks into the mass air flow sensor as well as still uses the narrow band O2 sensor to calibrate things.and yes I can hook up a laptop to it and drive it and look at exactly what it's doing throughout the RPM range as I'm driving it. I can also record my driving sessions.the one thing that has changed is the methanol that I was using before.I'm trying to do some readjusting maybe add a little bit more methanol and see if I can richen the mixture as it kicks in about 8 lb of boost. Brad did the setup using a windshield wiper fluid that used to be able to get at pep boys that was 10% methanol and distilled water and now I can no longer get that particular mixture. So I'm having to make my own.I'm actually going to go out right now and make sure the throttle position sensor is set up correctly. I'm pretty sure I checked it a couple of months ago and it was set up properly but I'll double check.it's just so strange that it ran great for so long when I never touched anything I didn't even change Brad's tune there was really no reason to go in there and mess with it. Thanks for the response I appreciate it.what I noticed yesterday is it seems like first and second gear have plenty of fuel by the time I get into third and fourth is when it starts leaning out.I actually adjusted the methanol to kick in later but I haven't had a chance to drive it yet. And now it's going to rain for the next 48 hours.and since I've never touched Brad's tune I'm just really nervous about getting in there and changing numbers around and screwing something up even worse. Brad did save his file on my laptop so I can always put it back the way Brad had it.
