hmm. now you have me thinking i dont need a custom chip. i was thinking of getting a custom one because of the TC lockup deal.


i HATE the fact that i can go through first gear nicely, and it will shift into second. whatever speed the engine was at before it shifted into second, it stays there and just grinds away for a while, and then the TC locks up, and then stays at the same RPM some more. sounds like a CVT. third gear is basically the same way. plus OD and TC lockup occur at the same time, and that gives the huge rpm drop.

does your chip correct the symptoms i mentioned above, i mean does it lock the TC on acceleration in second gear? if so, its sold. i want acceleration proportional to engine speed, and i want the TC to be locked up on acceleration. more of a manual feel to it.

all i need to do now is get my gauges and have the manifold hole ready to fill. i can then drive around with the evolution on 60/80hp while i sell my attitude/juice, and get the money for a chip. one more thing i think about while typing- when going into acceleration from about 45mph, the engine is in OD, about 1250 rpm's or so, correct? does the chip unlock the TC with some pedal input, so it doesnt grind away and try to make power at 1300 rpm? if i hit the OD button, it will go up to 1800 or so.....

sorry to be nosey, but can you PM me how much you paid for the 6 position chip and where you got it, if you do not feel comfortable saying it in the public forums? thanks.

 

JT's prices are listed on his website.

 

I'm pretty sure it's 256 MPH, but my antenna keeps bending too much when I take it much above 225... LOL.

 

that made my day.


you know that you would probably need .50:1 rear end ratio to spin that fast!

 

Great info guys, I too will be setting the Predator on the bench for code purposes and going with a Jody chip. The tranny and t/c problems are such an annoyance, I just cant stand it much longer. I think with a manual trans the Predator is probly real nice, but the auto is a no-no... Got to save for that now!!! You guys are killin' me...LOL

 

Your description sounds like mine BEFORE I put in the Factory Tech accumulator - soft, horrid shifts, a slushbox. Couldn't tell if it shifted gears, or was just freewheeling between them. If you don't yet have the Sonnax valve mod (cheaper than the Factory Tech) in your trans, you need to do that. Jody can adjust line pressure with the chip, but the hardware alteration works better.

With the shift mod made, mine shifted crisply in all gears long before I contacted Jody Tipton. The DP Tuner chip didn't make the shifts crisper - in fact, Jody deliberately did NOT add any line pressure adjustments because of the shift mod.

Instead, it shifts more as I think it should - the OD shift and TC lockup are now separate - at least in 'tow' mode. I haven't had time to really test it out yet.

 

i do have the sonnax valve/ tricumulator valve

 

what are your egts doing with the chips is my only question?

 

Hmm. Then perhaps you should contact Jody and see what he recommends for trans tuning for your setup. Mine was easy - no tuning for shift, just TC lockup - which, after driving it to and from work for a couple of days, just feels great.

I had to spend some time on a twisting country road today, speed range 35 to 55mph. Locked out the OD, and it stayed in 3rd with TC locked the whole time - well, except a couple of times going up a hill when it downshifted to 2nd, then back to third, and the TC remained locked. It's not a manual trans, but at least now the TC doesn't unlock stupidly.

 

I have an 80hp chip and combined with my mods i see no more than 1100 degrees avg for maybe 30seconds while pulling a 9000lb TT uphill. 1250 is the redline.

 

I haven't pushed mine hard enough to really tell anything yet - except that the temps are noticeably lower in the 40hp tow mode than in the Edge's 80hp race mode. If that doesn't seem a fair comparison, then try this - my seat of the pants accelerometer (yeah, yeah, not very scientific, not very accurate) tells me that the DP chip 40hp mode has at least as much, and probably more torque than the Edge 80hp mode.

But it is deceptive. The Edge seemed to jump more at the slightest pedal press, but the DP chip seems to build more torque more smoothly and more consistently. I'd love to see dyno test results.

I'm hoping to have time to play with it later this week. If I do, I'll post some EGT results.

 

yes torque converter lockup. that is what i want, because shift POINTS seem fine. did you call/email him directly and ask for the lockup feature (at no extra cost correct?) or did you just buy one off the shelf from a retailer (such as ITP diesel) and that already came with it?

 

I would call Jody direct @ 828-221-0076 and ask about your TC questions. If it is included in a standard tune than ITP can burn it for you.
If you need anything special, Jody can tweak the tune and should be able to e-mail it to Dennis at ITP for the burn.

 

thanks.

now all i am waiting for is my gauges to come in, so i can take out the juice and have gauges to run (plus to fill my hole in the manifold) with the evolution until i get the chip

 

HeatStroked is right. Just call Jody directly. And, no, the TC lockup didn't cost any more.

You can order the chip from ITP, or directly from DP Tuner. I checked - the prices appear to be the same.

Anyway, I hope you are as happy with the result as I am!!
