This 91 octane test car doesn't happen to just be using stock injectors does it?

It uses FIC 770cc injectors from our standard fueling package. The fuel pump is stock.

Question regarding this 91 octane tune (and your base map in general).

If someone were to purchase your turbo kit, along with the fueling package, but were unable to visit your shop for tuning, and/or doesn't have a trusted tuner local, What would you recommend for getting the car up and running, and safe for daily use (and 'spirited abuse')?

Would you consider the base map that you currently provide (and will for 91 octane, I'm assuming) trustworthy and safe as a final tune solution? Would you say its necessary to visit a trusted tuner/dyno for fine tuning and/or monitoring? Or only recommended? Would 'e-tuning' be a reasonable solution?

Thanks in advance, and I'm looking forward to seeing the 91octane results!

Your best/safest bet is to find a tuner relatively nearby that has a good reputation and knows ECUTEK (and preferably this platform). From what I understand Speed Density tuning is highly sensitive to differences in motors/setups etc. This kit requires Speed Density tuning due to the smaller MAF diameter.

The drive down Friday night and a hotel room, or super early drive Saturday morning is well worth the peace of mind when it comes to having a perfect, in person tune by someone who really knows their stuff. I'm not as far as you but I still drive 3 hours in traffic to have toan tune my car because there are far to many horror stories on this site of destroyed motors from poor tunes. Some are even in person tunes, not just e tunes. Hell, my car is at Ptuning right now getting the flex fuel tuning finished up

I don't understand why one couldn't just rescale the MAF tables to the new size to continue using both MAF and Speed Density as the stock car.

what would be the highest PSi one could run with the base map?

and if WMI is added what PSI ?

Oh sorry man, I keep neglecting to update my profile. I'm no longer in Jersey. Driving to see Toan would absolutely be my plan if I were still there.

That is what they do. They use both MAF and SD. But you can't just use MAF since it will be maxed out with this setup.

We do currently offer E-tuning on our turbo system, when used with our recommended fueling package. We base the etunes off of maps that have been refined using data collected off of our many local dyno tunes. We just finished up our base 91 octane map and can now etune off of that map too.

Due to the many variables involved with tuning this platform, especially considering that we are converting an originally NA car to FI, we recommend final tuning for optimum results. We do offer base maps that will allow you to drive your car to a local tuner or to start your etuning, but the only truly safe base map would need to be somewhat watered down and will not give you the results that our turbo system is fully capable of.

So the base tune provided will be good enough to get going and stay safe, and then several revisions can be made via logs and emails direct from you, all the way up to the final product?

End users want the ability to run a BOV without having to recirculated it. Also, companies like ourselves want to be able to run a 4" intake system with our GT30XX turbos without running the small stock MAF housing as a draw through MAF set-up.

With that said, 99% of FI companies run a blow-thru MAF for the reasons listed above. Most of us also weld our MAF housing to the intercooler pipe. We do not want to to run a 3", 3.5", or 4" upper intercooler pipe, just to keep from overrunning the MAF sensor as we up the power. Doing so is plain silly, not to mention the MAF readings totally suck when you run a blow-thru MAF housing larger than a 2.5".

The central TB location on an FA20 engine doesn't allow you to build a proper 3" blow-thru MAF with a straight section that allows for non-turbulent MAF readings. A 2.5" MAF pegs 5 volts at around 260whp on our dyno on pump gas. This is not going to cut it for us. We can go to a 3" to try to achieve 300-350+whp, but the MAF readings will NOT be stable. You'll go around in circles trying to zero in on your fuel trims.

So with that said, what's wrong with a running hybrid MAF/speed density tune?

I'll try to answer this when I email you your starting base map.

Yes, that is correct. You will also need a wideband in place too, but we can go over that before you're ready to start tuning.
