Had a talk with my tuner and they aren't too high on the reflex kit. They did one for a customer a while back and said they were hard to tune to get them to ramp up easily its like a straight hit once in boost. I have been reading everyone's posts you all have mentioned that you have to play with the curve to get it to ease in but what are your thoughts?

You have to setup the cars ECU to never have positive long term fuel trims when going into PE mode. Then also set it up so so that you have plenty of fuel room for ethanol % increases and weather(meaning DI spray window SOI-EOI). And then you dial in the port system similarly as you would if running meth as a fuel source. It does take a little bit of a dance between tuning the ECU and the Reflex but I wouldn't call it "too hard" by any means. Maybe the tuner didn't want to take the extra time to deal with it. Maybe they haven't used the newer closed loop WOT feature. Maybe they know about the DSX Kit that is coming out and prefer to wait and see if that is easier to work with. |

For me it was really pretty straightforward. All I can say, is if *I* could figure this out by myself, with only a little basic info from folks on this board, a true tuner should have no issues with it. The ramp-in is a product of the MAF curve in both the Reflex and the ECU. The spreadsheet supplied by THPSI takes all the guesswork out really. It couldnt be more simple. Ok it COULD be more simple, but it wasnt hard thats for sure. Theres about 1000-2000hz wide "blend range" built unto the spreadsheet were the DI tapers in less, and the reflex tapers in more. In my experience the "blend-over" happens in an area were you dont hang around much anyway. The blend-over happens on mine from about 8khz to 9.5khz and most part throttle is below 5-6khz with procharger, and WOT is 10khz and up. I suppose with road-style racing it might hang around in the blend area more where you are holding lower gears and feathering throttle, but even then its really not a problem because of the MAF math. The physical cross section where the MAF sits will affect the blend start point, with the 4" (i think) cross section of the PC intake tube being smaller than whats typical with a PD-style SC. I think on a PD the cutover starts around 6khz. Maybe the DSX will be better/easier IDK, but the Reflex THPSI is not a hard cut into PI.

My case was complicated only in that hardly anyone, either, talks about it, or actually uses it.
I've come to the conclusion that the method I am using (and still, mostly, using) is, as far as I can tell, limited by the stock cam, and specifically - the fuel pump lobe. I'm updating my thread with my current findings and understanding, but, as already stated - that's more my method and combination more than anything, IMO. Any competent calibrator should be able to get this set-up going, and A LOT of information has been shared my MANY people in threads in this section. IMO - if your tuner can't get the Reflex to work, I think you should reach out to a couple people here who can help. If you read what they post, you'll know who you can go to.

I'm currently reading through your thread now. I think your situation is slightly different being a Zl1 (1 being the cam lobe) but same concept. Just paid closer attention to the other 2 being an SS like my setup. Either way each thread is showing me things to pay attention to so that's a big bonus. If I haven't said it already thank you to the 3 of you and everyone that has offered some incite on how to approach the adjustments.

I just realized you're in NC. Pray Performance might be someone for you to reach out to in regards to tuning. He does the conventional style of port add in, opposed to the way Radz28 and I do it. From our conversation he's been doing more and more of thpsi setups and having good success with them.
