I am new to porsches but have a lot of modified car experience. I have a TPC Blitzkrieg car. (modified vtg turbos, exhaust, header, intercooler) The TPC tune was throwing errors (lean at idle) and TPC wanted $3k to maybe possibly sort it out, so I'm back to an OEM DME because I needed to get the car working and take a guess how much trouble shooting and throwing new parts at it we did before replacing the DME. I'm extremely against paying 3k for a proprietary canned reflash again.

So far I see my options as:
(used) Pro-EFI pnp@ $2k + dyno tune: ProEFI claims that if properly tuned, this setup will retain ALL stock functionality and driveability. Is this true? Be nice to be able to replace the FPR, add ethanol sensor and go e85

OpenFlash Tablet @ $800 + Dyno tune: I have a ton of experience using TunerPRO and would be very happy to have hardware that would let me use this software on my new car. That being said, I'm worried about finding an experienced porsche tuner who will work with this hardware. I want to stay out of the politics here, but finding an experienced tuner nearish to NYC is a concern.

Cobb Accessport @ 1800: Not really open. would probably give me nearly all the power with none of the headaches with a canned tune and can get proprietary dyno tune. At the very least this setup wouldn't try to charge me 3k for a reflash on a canned tune.

Durametric @ $287: I'm not quite sure what I can and can't do with this option. Does this really seem a viable option for tuning a modified car?

I'm leaning towards either the proefi or the openflash, but I'd love to hear from more experienced people here.

disclaimer: I bought the car with TPC stuff already on it. While I'm not thrilled with the way they handled it, I have no idea what someone did to this dme+tpc tune before I got it. It had the REVO SPS+ which means it is somewhat user mess with-able.

 

Like you've already noticed, a quality tune can make or break a car's performance and drivability. Regarding your options, the ProEFI is probably the best answer if you can budget it, especially if you're considering FlexFuel.

There's actually a handful of ProEFI users in the Northeast area, majority of them coming out of Garth/Undercover Performance. Most of them are running it on 996 Turbos, but that'd include: prodigymb, 32krazy!, TopGun, DSCOFF, and 2swoosh, but they've all praised how professional Garth was with setting up the ProEFI and tuning their cars.

I know the OpenFlash development is more "native" to the West Coast, so there's probably gonna be a support issue (and a tuner familiar with their software) on the East Coast. A better option might be Eurodyne (maybe from Tim941NYC) or an EPL custom stock DME tune.

 

We have accesstuner race so you can tune the car yourself. Also always adding features plus we have over 60 tuners for the porsche platform.

Shoot me an email if your have questions. I am alwas up to help guys trying to set up there own cars.

I'm really interested to hear from the ProEFI guys on daily drivability/stock systems integration. Maybe I'll give Garth a call tomorrow. I've already ditched factory audio/nav, so I'm not worried about that, and pasm is a standalone system, right?

Thanks. I'll look it over. Does this come with all the cobb canned tunes available for modification or not?

 

You can modify any of our OTS maps with the software, so it gives you a good starting point. I have also met with some guys for some one on one time to help walk them through it as well.

Let me know if you have any questions!

Did you buy the car with those modifications or did you have them modified at TPC after purchase? Throwing a lean condition at idle error could be caused by many things not just the tune. My point being that if you bought the car that way, don't go chasing an issue where there might not be one.

 

Bought the car with the TPC modifications. Your advice is exactly what TPC said, and what every reasonable person, including me, said before I spent 2 months constantly in and out of the dealer shop. In desperation and on the verge of trying to return the car to the dealer they decided to throw in a new DME. Fixed it.

Moot point now, because the dealer said I could keep the working DME or the Tuned TPC flashed CEL every half a tank one and at that point I'd had my fill of headaches and taking the bus home from the dealer, so they reflashed it to oem and that's $3k/100+hp up in smoke but at least it works now.

 

Glad you got it sorted.

 

These cars are not difficult to tune. Access Tuner Race on the Cobb platform works great.

Not a lot of people on here talk about them, but if you want a standalone look into Syvecs. Anthony's 1700hp car is running one currently.

 

Was one of the first ones I came across. It doesn't support VTG turbos, so wouldn't work for me.

 

Ah, the VTG compatibility slipped my mind. I'm a big fan of the Cobb but 2k for a complete ProEFI sounds like a very good deal?

Also, the Durametric cable/software is basically a fancy OBD2 tool. It can do some basic service related stuff and datalog. You can't tune the car with it.

 

I looked into this with Ryan @ Syvecs, he actually just posted some information about the new version of the Porsche ECU and they do support VTG control now.

 

These car's are VERY hard to tune if you follow the same strategy the factory does.... which few do.

 

Can you expand on this statement? Keen to understand more.

 

Why did i not know you were local and had a reasonably priced reflash special price a few months ago.


Any advice for my current predicament? Every try the openflash? ProEFI daily drivability?
