edge Evolution tuner

[Vitucc]

Hi memebers,

I recently purchased a egde evolution tuner. I must say this thing is kick ***. I am very pleased with its performance levels. I upgraded from a very old superchips tuner. My truck ( excursion) currently has guages m mbrp enhaust , and a full intake. my question is my old superchips programmer made my tranny shift nice an firm , and the edge evolution is not quite as as firm. am i at risk of transmision problems ??? i heard there is a valve body adjustment and a better torque converter out here for the truck. its a 7.3 any suggestions.

Thanks,

If you have the 15001 as I do, it will allow you to change the shift points as well as firmness. I don't know about the 15000. Read the manual.

turning up the line pressure is not a great idea, if you read enough you will understand why. Get a transgo tugger kit installed and never look back!

I understand what the tugger does and would also highly recommend it, but "lightly" adjusting the line pressure isn't going to kill his tranny. The right foot(and going stupid with line pressure without other mods) is what will kill it. That's what his old superchips tuner did to it. I've been building transmissions since the pg days, and I've built more 4r100's than I can count. That's why mine has a built valve body and tc in it.

Hi ,

Yes I have the 15000 version of the edge evolution. I guess the ols superchips was a little better for the transmisison. I am going to do alittle more research on the transmission tugger. Powerstrokeone what did you do the converter and valve body ? Since you have built trannys am iin danger of ruining mine.

I went through mine with a master kit from RacerX. I am very pleased with the quality of parts in the kit. Torque converter is a 6.4 converter. Little higher stall than the 7.3, and much stronger. The converter is the biggest problem with the 7.3 automatics. I'm not saying the tranny's are the greatest, just that the converter is the biggest problem I've seen.
I have no idea regarding your transmission(mileage,maintainenence, use/abuse), so I cannot answer your question whether or not you are heading for trouble or not. Assuming that the tranny doesn't have a ton of miles on it and has been serviced regularly and not abused, you should be fine. As a member on another forum stated this very evening, "don't use the right pedal as an on/off switch or a boost launch" and you should be fine.

I agree, light pressure adjustment with a fixed valve body is ok...with discretion. One thing I liked about the tugger kit is the option of drilling and re-drilling the plate to get firmer shifts vs raising line pressure. When I first installed my chip, the initial trans setting felt exactly like stock. I believe my tugger plate was drilled to .040 and it feels perfect, quick snappy shifts but still smooth in all throttle positions. I also installed a twin disc torque converter since we had it pulled out anyways and there was a bit of brown patina on the tc case.

I don't know about the woods valve body, but I ran a Greg Evans factory tech VB on my lightning, and there was ABSOLUTELY no need to raise the line pressure. The 1-2 shift could hurt your neck with good traction and the 2-3 shift would bark the tires. 20,000 miles later it still shifts perfect, stock TC too.

Alright so on my way home tonight my transmission feels like it starts slipping. I get on it and yup its slipping. Pisses me off. I take the brand new edge evolution programmer out and the transmission is ok ? I dont get it. Anyways im into a transmission. I have done alot of reading on the tugger kit valve body and the notorious torque converter issues. So here are my questions. The tugger kit yes or no or other companies . Torque converter do i have mine built with a 3 disc and have them lower the stall speed to 1600 rpm or look for a 6.0l one. I am probably going to do this next week so ill start ordering all the parts for it then send it in for rebuiild. Again I have a 2002 excursion with a mbrp exhaust and a full intake. I bought the edge evolution 15000 programmer. I do alot of towing in the summer with this truck. PS anyone else have this issue with this programmer ? Post away and thanks for all the replies in advance.

Vito.
