The ultimate LT1 $$EE patch thread

[kur4o]

These are the latest files I have.
The xdf contains the zero tps open loop patch V2. Tested and working good.

Now the latest eehack exe contains all of the available patches[v5], so what you need to do is just flash your bin with patches checkbox enabled. If you want to use flashhack for flashing after that, than read the patched file and work from there.

With the v5 patch applied you can use some very good histogram tables with tunerpro adx for maf tuning. My favorite is maf cell vs average blm vs blm cell. It clearly shows that one size fits all in maf is vey hard to reach and some closed loop is mandatory.

Too bad we cant export eehack log files to tunerpro format.

Steveo any chance you can make some log conversion application.

I think steveo mentioned he was adding MAF tuning tools in his v5 of EEHack. Neat stuff though!

Steveo any chance you can make some log conversion application.

maybe, do you have a good description of the xdl format or should i reverse engineer it

[kur4o]

No idea about the format. Open an xdl in hex editor and look for some patterns.

I have a 94 auto, which one should I be using? I dont want to control it via a pcm pin, I want it in open loop at 0 TPS all th time so i think it is between these two.

Definitely use the v2. It is much better and you can add a mph threshold for low speed open loop too. I run it with 5-6 mph threshold with great drivability.

Switch the xdf to category view to find the threshold scalar. Pcm pin is optional and you can wire it any time you want to run full time OL[switchable] if needed.

[NorthernCrew454]

Sounds good, if i just apply the patch and dont touch mph threshold it will just go to CL once 1MPH is reached right?

one other question - do i always need to use this xdf for tune updates or can i patch it and go back to using steve's xfd after?

[kur4o]

Apply patch and save bin. Than configure

max MPH THRESHOLD for forced zero TPS Open loop

to your preffered settings. 4-6mph is the way to go. It is really needed on deceleration with throttle off. That is the reason I put it in there.

You can open the scalar after the patch is applied and check what it is set for.


ONce you apply the patch and save bin, you can edit it with whatever xdf you want. Make sure you use the same patched bin after that.
