I'm switching tuners. And don't want to say until after car is tuned lol. In case car blows up haha. I'll let you know Monday afternoon. I'm located in Houston though. Not sure where you are.

Just crank the meth up and you'll be fine.

Just to be clear, this isn't an ECS kit issue. All kits have the same exact issue with mafs.
Even NA cars have that issue.

I always wondered if the dent right before the MAF on ECS's tube makes MAF readings worse at lower airflows. I tried to order one without the dent but they didn't have any in stock and I didn't feel like waiting, so I just got the no MAF version.
Guess I'll probably never know

I am going to play with blending the tune this spring but won't switch to SD only. MAF has been flawless on both my supercharger systems so far.

Well, it isn't an ECS exclusive issue. Other kits, and intakes have same issues. If maf isn't in a good spot, lot end/tip in/etc can suffer.
I never had an issue with running maf only. Drove great. Just SD drives better.

SD mode needs a MAP sensor capable of reading boost. A ZR1 sensor is an easy option for most.

An eforce comes with a TMAP. Map and temp sensor in one. It is in the rear of the blower and works perfectly. You will want to tune with it.

Can the car be used to MAP only at idle up to a certain throttle percentage then switch over to MAP/MAF combo? I have HPTuners and am still on the learning curve here.
The car is an '09 ZO6 and the mods are as follows:
- Halltech MF103 Intake
- Nick Williams 102mm TB
- MSD Atomic Air Force Intake Manifold
- Advanced Induction 280CC heads, BTR springs, Ferrea 2042P Exhaust valves
- EPS (Engine Power Systems) custom grind cam - 232/246 duration, .639/.639 lift on a 115+3 LSA
- Kooks 1 7/8 Long Tubes, 3" Catted X-pipe
Current drivability is bucking off idle and any cruising 1500 rpms and lower has a lot of surging.

I agree the camshaft is the source of the surging and poor idle quality (reverse pulses through the MAF totally confusing it - you can see it on the log play back via wide frequency range all at idle).
I want to try MAP for idle up to about 1500 rpms then switch over to the MAF/MAP combo that is currently used. Does anyone know the specifics how to do this in HP tuners? I have a wideband so I can tun the MAP table once the MAF is disabled, but I would like to keep both sensors active in case one fails.
