I have a Edge CTS with the canned tunes with the latest update from edge. ( just updated 2 days ago) I have been running it on level 2 with custom programming. Only thing I'm changing is Tire size, Speed limiter, and WOT fuel.

Problem is, (**and it did it before the update**) under WOT its not shifting out of 2nd unless you let out a little (to maybe 85% throttle) and then it shifts.

From a stand still punch it shifts out of 1st at 5400 RPMs and hits the rev limiter in 2nd about 5500 RPMs.

I Tried turning the WOT fuel to stock, still did the same thing.

I tried raising the rev limiter to 6000 RPMs and it just hits the revlimiter at 6000.

It doesnt do it on stock, I'm just wondering if I have an issue or it's something stupid.

I'm kind of at a loss, any info or thoughts would help!

 

Texas, I have not updated the firmware in my CTS, because it would wipe out my custom tunes and I'm operating on the principle of, "If it ain't broke, don't fix it", so, I have to ask a question.

Do you now have the ability to adjust the WOT shift points? If so, check where they are. I suspect they might be in the neighborhood of 5100 or higher. If that's the case, reduce the WOT up and downshift shift from 2-3 to 5000. Put the 3-4 up/downshift at 4600.

Leave the Limit RPM at 5500. DON"T go as high as 6000 here. According to Mike Troyer, the Torque Converter starts to balloon at 5400, so you only want to go briefly above that point, and I would not exceed it by much.

Now, unless your WOT 2-3 shift is set WAY too high, I'm puzzled that it won't upshift with the rev limit at 6000, so maybe it IS set too high.

I still have my older monochrome Gryphon (upgraded Edge) and I can tell you I'd hit the rev limit too on the 2-3 upshift if I had the shift point and the limit closer than 400 RPM (mine are 500 apart). The shift is actually "commanded" at the shift point, but that releases the clutch which causes the engine to rapidly speed up. If it hits the rev limit, the shift won't complete.

Thanks for your reply jack,

no you still cant adjust the WOT Shift positions, Its all basiclly the same it just has TCM programming for each level. (Unless I am missing something in the menus, If I am some one help me out!!)

The only reason I raised my rev limiter is to see if it would shift with the higher limiter, but Its like it would keep going past 6000 RPMs if you didnt limit it there!

This is only my 2nd auto Ive ever owned, What do the shift by? Speed? RPM? Sorry If this is a dumb question, but I dont know much about autos! If it shifts by speed could my tire size cailbration have something to do with it?

Another dumb question but Ive read stuff about programming while the vheicle is too hot, Its been 110 degrees here with 120ish heat indexes. I programmed my truck while it was cold (the engine) and about 95 outside. Could it have anything to do with Temp?

 

I was also reading about making sure everything is off and doors are closed and no electronic devices are near by. The last time I programmed it the radio was on using bluetooth audio off of my iphone sitting in the console and I had the doors open. I think I'm gonna program it back to stock, unplug the battery for 15 mins and try programming it again. level 2 leaving everything stock besides tire size.

 

still hitting rev limiter, it does it from 3-4 under WOT also....


Here is a video....

 

Texas, it sounds like you're doing things right, but is there any parameter you can change in the transmission in "Custom Options"? If so, what are they?

Now, the shifting:So, if your tire size or gear ratio is wrong, your sensed speed will be too and that does screw up the part throttle shifts.

Changing the program at 95 degrees with the engine "cold" sounds fine to me. Your symptoms do NOT sound like a programming "failure".

I'd call Edge about this. I personally think they've got the WOT shift points set too high in their canned tunes. I know for a while they had the rev limit set to 4200, or some such ridiculous figure, and naturally that caused problems.

Edit: My truck will not shift up from 3-4 at WOT either, no matter what the RPM. Bill Cohron once said you'd need to be at about 120 MPH for the shift to happen, which is what makes me think there's a lot more to this than just engine RPM.

Jack, Thanks for the info, That make a little more sense. Im thinking your right about the WOT shift points being set to high. I emailed edge, but I'm thinking I may just send it in to PHP to get it converted to a Gryphon. I've been wanting to do this for a while and I think with the custom tunes the problem Will be fixed.

 

You will not need to send the unit to php and have it converted.....its a cts not a monochrome edge evolution.....

The only thing you do is fill out an order form at www.gopowerhungry.com with all your info....then submit with payment and wait for Bill to email you back that they are done.....

 

Ok thanks, I had Already emailed them because I was kind of confused. but that answers my question! I filled out the form.

 

And, tell Bill about this "shifting" issue. I think he might be able to set things up to fix it. (At least the 2-3 upshift part). Since you have a 6-speed transmission, he may be able to do something about the 3-4 upshift too.

I sent him a email telling him a little about it and a link to this thread. I'm not to worried about the 3-4 WOT Shift because thats close to 100mph, But I still would rather it ever hit a rev limiter and fall on its face! Thanks for y'alls help!

 

hey guys i have a few questions not to thread jack or anything but its about the same topic. I would like to order custom tunes from php but I already currently own a edge cs and I cant seem to find this listed under products or anything on there website. Should I contact them directly or what ? I have a 2010 f150 5.4l

Thanks for the link that clears some stuff up.

 

Did you guys ever hear from edge about the P1602 Immobilizer/ECM comms error. I just checked my DTC's and had the same thing.
