Some of their boxes are faulty. I also have one that doesn’t work correctly. Misfiring when we turned on PI. We swapped in my backup box and it worked fine with no changes.
was not the first time the shop saw this issue and I’ve heard from other shops they have issues as well.
Yeah ms109. They said the 611whp was equivalent to about 650whp on their previous dynojet.
For reference I was hitting similar speeds as Jackie’s supra on the straights at Gingerman (when he last brought it there). Slightly different aero setup but equivalent tires.
That’s the original gen 2 ultraflow. It’s similar to the Flow Max but has a slightly smaller compressor wheel.
Here is the new Flow Max dyno with PI. It was done on a completely different dyno which AMS says it reads 6-7% lower than their dyno jet.
in terms of real world, I consistently gained...
Having trouble with the reflex box. CAN communication is working now (shoutout to @Zupraman for the help!) but there are misfiring issues with PI is switched on... hopefully today it gets fixed and tuning is finished.
Didn't bother reading all the way through, but it's hilarious to see the drag guys argue with circuit racing guys even though they use the manifold completely differently.
Drag guys - use the cooling system as a giant heat sink for 10 seconds (or less)
Goal: pull as much heat out of the charge...
New Flow Max went on my car last week. Dyno was earlier today but still some issues with the Reflex+. Hopefully will have it all resolved in the next couple of days and I can post results.
I also have a new ETS 4" GESI catted downpipe with 4" exit (not compatible with oem-style exhaust) that I can sell shipped for $950 or local pickup $850
