If the tune is too aggressive then it will show bigger gains but bad to run long term.

Generally a custom tune will always have more gains over the OTS tunes. Finding a tuner willing to use OFT locally will be a challenge for sure. I rather just run Ecutek. I've been very pleased with my custom tune from Moto-East

+1 very interesting, pretty significant gains! Hopefully this won't turn into an EcuTek vs OFT thread, rather stay as an OTS vs Custom tune thread.

Fair enough. Just wondering since you didn't say anything other than mod list and dyno comparison.

As for OFT vs Ecutek and people thinking it'd be magically different, if it modifies the same maps which I don't see why it wouldn't (since NA), there is no reason why it would be any different. The difference here would be OTS vs Custom Dyno and different tuners plus their tuning philosophy. I have no idea what the TopSpeed guys goes for, shiv's has been fairly vocal and logically sound.

Basically you could have had the same result without paying for ecutek if he was happy to tune using Romraider(OFT flashes the tune).

The thing that is nice about the OFT is that you can sell the tablet eventually and get some money back. With a custom Ecutek tune, you really can't do that other than sell the cables or something. So I would rather have a custom OFT tune than a custom Ecutek tune.

Corrected.

I'll be curious of the difference once the 2.0 maps come out with the dedicated 93 octane maps.

We'll know soon enough, but I doubt we'll see 10WHP out of this. Maybe 2-3 at most. He still has to be very conservative to cover everyone.

This map proves that NA is the way to go on these cars.

Depends what you're aiming for.

Good work guys. Would you mind posting up the dynojet run files (.drf) from the custom tuning session?

As soon as I can catch Doug off the dyno i'll definitely check. FWIW i was really happy with the OFT tablet and i'd be super interested to see what if any differences exist when an ECUTeK vs OFT tablet are tuned side-by-side.

I've tuned both and gotten the same results with either. For an NA car the end result is exactly the same, since you don't use much if any of ecutek's custom mapping stuff, the process is pretty much identical. Same goes for using romraider and a tactrix cable. The only difference lies in the software interface, flash times, workflow etc.

What are the differences in tunning with ecuteck for forced induction from openflash?

Speed Density, custom maps for things like boost control, real flex fuel, AFR failsafes, overboost fuel cuts, boost by gear, better traction control. The list is endless, but pretty much boils down to 'custom maps'.

The real big thing though is speed density, which gets you around the MAF limitation, and the ability to use custom maps to overcome the port injection limitations at high power levels (typically on e85).

Also, just in my personal opinion i wouldn't be comfortable tuning a turbo car without an overboost fuel cut. Mine has already saved my motor a couple times, and i know a couple guys who didn't have it and it cost them a new engine. Not worth not having, imho.

Now with a supercharger the math is entirely different. The vortech kit works great. The JRSC kit, not so much (the MAF is maxed out of the box). The kraftwerks kit seems like it would be fine, but the bigger blower also maxes the MAF in the default configuration, necessitating SD.
