Is there rly a diff other then price and that the DHP has a 2min fan on after turn off and the zzp only has a 90sec.

Quality/performance wise... does it rly matter which?

well if you buy a DHP pcm, and later either buy a tuner or have someone tune your car, you wont be able to use the file. this is cause dhp locks their bin files.

ZZP doesnt lock their files. so you can make changes later. another i would recomend is: http://milzymotorsports.com/

fan time is not all that important... and im sure if you email either company they will adjust the file to your needs.

DHP is proven and true... I'd recommend them anyday for tuning because that's all they do.

ZZP tuning is like Walmart's auto service center. It's okay and it'll probably do the trick, but it's not their specialty, so it's never gonna be AS good.

Also whats up with CASE learn...

o and ty for the insight but im basically at my starting point... 1for zzp 1for dhp lol

By looking at the files, the only significant difference I've seen is that ZZP eliminates every bit of the Torque Management in their file. Good for speed, bad for tranny longevity.

How bad are we talking here?

Case learn is matching the crank sensor to the PCM. Most don't need it.

How bad are we talking about? The people that are breaking trannys are the same ones who are out racing and performing many hard launches. Also many people suffer tranny failures afterwards not because of torque management issues but from increased line pressures. But those ones are all ready on the weak side and can't handle the extra pressure and fail earlier then if no PCM.

As for which PCM manufacterer is better they all have their differences but As for the quote ZZPs is the wal-mart version DHPs is as well. Any PCM you buy from any manufacterer is going to have a generic program cause not all cars are the same. And to get everybit out of a PCM you can you need a programmer to custom tune your PCM to your car.

I believe Bobby has used both DHP and ZZP but has since gone with the one from Canada Overkill I think.

Iirc as for DHP and being locked I think they changed there policy cause the competition isn't locking them and they were losing out on business.

I have a ZZP PCM and have had no issues and am very satisfied with the product.

I prefered my DHP.

ZZP tranny settings didnt work with my car very well

DHP all the way.

Some have been having more problems with ZZP PCMs.

My ZZP tune was way off for my top swap... they don't add enough fuel in, 6* KR with the stock pulley and a cam, yikes!

After I got my custom dyno tune I didn't have any knock. Honestly, I'll never go with an off-the-shelf PCM again.

Intense -> DHP -> Overkill

I didn't like the DHP too much. It ran through the trans gears too fast. It seamed to be in a hurry to get to the final gear. My current Overkill holds onto the gears longer, which I like. The Overkill also brought my KR down to 0*.
I know I could have bought a PowerTuner and tuned it myself, but the only thing I would end up with if I started jacking around with the settings is a dead PCM. Overkill offered to re-tune my Intense for $80+$20 shipping, so I shipped it to him and let him do his thing to it and I'm very pleased with the results, although I could use a minor tweaking on it, to get it dialed in with it on the car.

I have no idea how the ZZP performs, so I really can't comment on it.

well is dhp the same that 3800performance sells ??

I bought the ZZP PCM over a year ago. It's now a tuned ZZP PCM, so not so much that same anymore. That PCM didn't perform great with my fueling for my cars needs. Therefore, tuning came into affect and my car is better than ever, with much increased fuel mileage and power.

a custom tune will always out perform off the shelf ones... when you think about it they need to make a program that will work for the majority of people.

almost like dynotuning, a custom tune will get things near perfict. there is always room for improvement, and also with weather changes your tune is also effected.

i will never buy a drop in pcm. im set on tuners. whatever the cost they are worth it. just to beable to set the shift points and adjust the settings the way i want is worth it. took a bit of time to learn but would do it all over again.

also with the ZZP file, most of the Tq managment settings they removed are under the performance shift section. in daily driving you shouldnt be in perf shift anyway.
