more sputtering

I would like to have the transmission strategy exactly like the 87 performance edge canned tune, and more timing than the edge canned tune.
I loved the way the transmission shifted with the canned 87 performance canned tune.Edge does not offer an 87 Performance tune. I assume you mean the 87 Tow tune (level 2).

I just wanted the timing curves to be a little more aggressive and the other standard items like rear O2 sensors turned off and speedo corrected, etc. Which I assume have not given you any problems.

When I got it, my converter was going in and out, so I had you lock that out until a certain speed, but now its killing what little gas mileage I had. Which is why "lock-up" torque converters are used. To increase fuel efficiency by transmitting all of the engine power to the transmission. I assume your transmission temps are a bit higher too now. I simply did what you asked for in that regard.

I paid the extra money for the gryphon, above the edge, because I wanted a tune that did everything the edge tune did, and more. I don't know what to do next. I'd like someone to call me so I can explain exactly what I'm looking for.

I'm making you a brand new program as soon as I finish typing this. It will be based on the canned Edge 87 Tow program with your necessary modifications made for your truck. Let me know how it works. I will post here when it's finished.

I realize you did what I asked you to do as far as the converter lock up. I'm just frustrated because I liked the edge canned tune, and I thought wow the gryphon is gonna be better than this? Awesome! Then it wasn't. By the way, I could've sworn mine had three tunes when I recieved it, just like the gryphon. (87 perf, 87 tow & 91 performance) My only concern with using the tow tune, and you might be able to correct it, but Bill was telling me one time that the tow tune had more fuel in it to keep cylinder temps down. When I tried the PHP tow tune, my gas mileage was totally in the toilet. Also, I would like the shifts to be much firmer than the edge tune. Will that have any effect on the rest of the transmission strategy? I hope not. I appreciate the quick responses.

I'm not sure how my last post came across. Talking on the phone and thinking/typing is not a strong suit of mine so it may or may not have been misconstrued as condescending. It wasn't meant to be that way.

Bill will always claim that he is far from perfect and that there is rarely a one-size-fits-all solution to everyone's needs. I am no different (maybe even moreso because I understand how it feels to be in that gray area where things are just "not right") and I'll be the first to admit that I am good at one thing and that is making mistakes.

Obviously, your truck hates our programming as it is. At this point we will have to make special concessions for the truck to get the tunes right (as they are ALL different and react differently to changes).

I can change the stock programming to account for what you've asked for. We will try it. If something isn't working right I will make the time to fix it.

Oh, and the stock Edge and Gryphon come with a transmission only, 87 Tow, and 93 Performance tune.

yep I remember now. You are correct

Does the 87 tow use the same fat fuel tables as your 87 tow tune? If so, is it possible to trim those down to the 87 performance level?

Yes, and I will be making that change.


By the way, how well does the C87 Tow tune you have work or have you run that one yet?

[stlhrse]

I have run it, but not towing yet. It seemed to do OK, for the short amount of time I drove it. If you don't mind, maybe after we get the performance tune worked out, you could just make the towing changes to that one. Don't do anything to it yet though cause I'm not going to be doing any towing in the next month or so for sure. I'd want to have the tranny strategy and throttle response from the edge, but more timing and much firmer shifts. I appreciate your help.
