Requesting a review of some log files.

[damanx]

Any thoughts would be greatly appreciated as I am wondering if i could get better mileage.

Specs on the vehicle are as follows:

1985 S-15 extended cab truck
1992 3.4 engine using edelbrock intake with the gm tbi 220 throttle body with the 4.3 injectors and running about 12-13 psi on fuel pressure.
700r4 tranny
3.73 geared rear

Using a modified ADSU bin in the 1227747 ECM. EGR is disabled.

It's been a while since I have messed with the tuning, but doing the old fashioned fill the tank up, drive, and fill the tank up, it appears that I am running about 22 mpg. The block has about 125k on it and compression is good on all cylinders. Everything else is stock.

I've included the bin file, a log file several days after the programming of that bin into the prom, and a log file from last night.

I'd say that 75% of my driving is highway.

Thanks for any help, and thanks to EagleMark for the help to get me this far.

you might try putting that highway lean cruise patch to your bin.

Found the thread about the highway lean cruise patch.

I'll do that this weekend and get some logs.

Is the ESC Done patch required?

[EagleMark]

ESC patch is more important!

There is a patch built into new $42 file so no need to do it the hard way as in that thread anymore.

Missed your post, sorry, I'll look at your log later.

So this new $42 has both patches done in a friendlier format?
