Re: 1993 F150 4x4 - Trans Tooning
Getting ready to move to my f3v2 chip to free up the QH. One last issue is the trans slams when doing manual 1st to manual 2nd shift but only when throttle is closed. Can that be fixed in software?

5.8L Belt Tensioner
I need a new one. Any recommendations on brands or enclosed/visible spring?

MPG Mode + EGR = Excessive Timing
Looks like FN1129 is causing it. Should I just zero it out or is there a good way to figure out how much timing is necessary?

Re: best new laptop for $500
Assuming you don't care about a touchscreen or 2in1 convertable.

If you can spring an extra 100 bucks:

Re: EESucka - found on ebay
I still think doing a UV erase / in place reprogram of the factory eprom would be the most useful development. I love the quarterhorse but being able to reprogram the box when done tuning would be amazing. Any hope of using something like this to reprogram it? I have a ECU with a bad injector driver I'd be willing to donate for testing purposes.

Re: 1993 F150 4x4 - Trans Tooning
Is it better to pull timing or add fuel when towing? I I'm thinking towing in first gear is going to be pretty light throttle once up to speed so it'll be running stoich. Should I just add some digits to the bdl table?

I figured this was easier than trying to decipher The first gear tcc functions. I didn't dive into it much but it's very different than the other gears.

Re: 1993 F150 4x4 - Trans Tooning
I used the development mandatory tcc lockup code to bypass the factory first gear tcc code. SW_MLK is now read from memory address 77e which is controlled by the patch code now. Lockup at 28 mph and unlock at 20 is hard coded but I made scalars to adjust as needed.
Code: Select all
794a: ef,27,28 call a174 Sub_a174 ();
794d: ff nop
794e: 39,42,0c jb B1,R42,795d if (B1_R42 = 0) {
Code: Select all
Sub_a150:
a150: 99,02,d9 cmpb Rd9,2
a153: d7,17 jne a16c if (Rd9 = 2) {
a155: b1,02,34 ldb R34,2 R34 = 2;
a158: 99,38,8d cmpb R8d,38
a15b: de,05 jlt a162 if (R8d >= 38) {
a15d: c7,ee,fe,34 stb R34,[Ree+fe] [77e] = R34;
a161: f0 ret return; }
a162: 99,28,8d cmpb R8d,28
a165: d6,04 jge a16b if (R8d < 28) {
a167: c7,ee,fe,00 stb R0,[Ree+fe] [77e] = 0; }

Re: 1993 F150 4x4 - Trans Tooning
Hold 1st patch worked out great towing today. She's got too much timing in her under light throttle above 2500 RPM. Started pinging pretty heavy so I pulled over and stuck it in low range and set wot threshold down to 250 for safety. Pulled fine the rest of the way enriched.
