If you must tune maf (ugh!) open loop is the way to go.

Id take advantage of the ZR1 map and go SD!

I don't understand your concern, whats the difference at WOT between an open loop and a closed loop MAF tune? Nothing, you are simply in closed loop at idle and partial throttle, as soon as you stab the throttle you're in open loop, what am I not getting here?

The MAF sensor, even with it being accurate can use some help from the oxygen sensors to keep AFR at stoich when you want it to be stoich.

WHo tuned it ? if it wasnt Patrick G . PM me i will give u his number. He will get it right

A personal friend tuned it. I'm planning to get Mike Norris to review the tune when I finalize it. Ayousef concluded my throttle body is the problem. It is lagging the desired position when spun up and I punch it. I have a TPiS in the mail, so I hope he is right! I'm also going to remove my high flow cats. Can't hurt.

I hear lots of good things about Mike, do I need to do some research in Patrick G?

[Whipped416]

no research needed , just the best tuner around that will spend the time needed to get it perfect!
TPIS is great.

you should see another 25 rwhp with the tpis over stock ..

I thought I looked. I sent in the ls2 core about 2 weeks ago.

Yeah, if you already had the LS2 motor, it probably wouldn't have been worth it as ours includes it. I put in the ZL1 section as those are the guys using this thing the most.

What issue did you have?

This one was on a built Whipple'd ZL1 and we only switched it because the customer wanted the billet bling of the Nick Williams.

That's the first negative comment I've seen on the TPiS. I hope I get lucky.

Must have been the 3 bad ones i sent back LOL

TPIS is Great to work with they helped Us quite a bit and provided us with Great customer service, and replaced all the units we had problems with.

All the ones we have out there now work well.

Moving One to the OP problem.

I believe what you need is to Tune the Predicted and VE Coefficient Tables and set them up for a 3 Bar Map as they are only set up for a 1 bar.

The Coefficient tables will fill in the void of the time between when the Throttle snaps open and the MAF actually sees the Air flow.

The Coefficient tables will provide the fuel based on TP RPM Air Temp and MAP without any input from the MAF..

I have seen this on Every Whipple Car we built, Until I did the Proper Tuning and All Gone.

Greg Banish Teaches this Technique in his Advanced Tuning Class.

You still Keep your MAF and Closed Loop and Enjoy all the Benefits without Disabling Anything.

Taught. Greg took a position with one of the big three and they don't want him freelancing. He held his Florida classes here at Redline.
