For sale 1987 Buick Grand National w/moonroof – I have had this car for about 6 years and in that time have invested a lot of blood, sweat & $$$. Car was pretty much stock when I bought it. For what it is, the car drives and handles quite well. Had the tranny done this past spring; new motor 2...

You look at your blms at wot ... the relative number from 128 will be the fueling correction (ie. 125 would be taking fuel out and 131 would be adding fuel).

Mine was set at 10.8.

Yes, using Razor's single nozzle setup w/ported heads, intake, roller cam, etc.

I have the Powerlogger, PLX and TT 6.0 as well and they do their job quite well. It makes tuning alot easier and keeping an eye on the blms at wot (with powerlogger of course) you can make fueling adjustments to minimize the correction. I can run 24psi with 0 knock on 91 octane.

That is locking pretty quickly, especially given that Powerlogger records at 20 frames a second.. Thanks

Thanks for your input Dave. What's strange is the car didn't do this when I was using the stock servo and my previous tc ... even with a pump producing lower pressures. Maybe I'll put the original servo back in there just to see if it behaves the same. By the way, how quiclkly do you see...

Ok, well here's the entire log. You can start looking around frame 484. Suggestions? Thanks

I wanted to give the detailed screen because you can see the 3rd gear indicator on it. Just look at speed, rpm and the 3rd gear indicator in the screen shots. Thanks

I decided to do some logging the other day as I wanted to see what the car would shift at on its own on the 2-3 shift. I was also trying to see what kind of drop in rpm I was getting on the converter lockup. Anyway, when I was close to the top of 2nd, it shifted to 3rd for a second, then went...

My line pressure numbers are low.

It looks like I need a new front pump assembly for my transmission. Anyone have any recommendations? Vendors feel free to PM me what you have. Thanks

Well I got some line pressure readings this evening. I checked the numbers at about 1200 rpm with car warmed up. R - 100(min tv) 275(max tv) D - 80(min tv) 210(max tv) OD - 80(min tv) 210(max tv) 1 - 200(min tv) 200(max tv) 2 - 200(min tv) 200(max tv) How...

Just thought I'd toss this Powerlogger file out there while I'm waiting for a tranny pressure gauge to check out any possible pressure issues. Wanted to see if the experts notice anyting out of the ordinary. The TPS is a little low at wot but looks to be driver issue :) . I get into it...
