ZR1 TB tuning issue
I have a z06 with a halltech cai, zr1 tb, maggy 2300, 1 7/8" headers, and off road 3" xpipe. I just added the cai and tb. The car keeps going into limp mode. Code being shown is tb home not learned or something like that. Any ideas?

I tuned my 2016 Z06 with ported blower, 2.3 pulley, afe cai, tony mamo tb, long tubes and off road x. I then took off the tony mamo and installed the zr1 95mm tb and the car runs great! I'm not sure why your tb has to be completely relearned. There's a procedure for it, so I would just have your tuner get it lined out. Good luck...

You've confirmed with your stock throttle body that the car starts and runs just fine?

Have you disconnected the battery overnight and then gone through the relearn process with the ZR1 TB installed?

No, I have a guy here locally that builds allot of high hp LS stuff, but is still getting experience with the lt tuning. He did my grandsport maggy and full exhaust upgrade perfect, then did the maggy full exhaust on my z05, tune was good. I think he's having trouble getting information for te zr1 tb. Span and all that.

I'll have to head to Nola to pick up some parts next week it you'd like to try a different tb just in case you got a dud. Really shouldn't need much cleanup for a 95 honestly

PD supercharged cars benefit much more from the larger TB then NA cars or cars running centrifugal Superchargers.

Mine picked up a little more as well with the ZR1 tb, but my blower is ported. They do say that if your blower is not ported, don't waste your money on the 95mm tb. It works best with a ported/pulley blower setup. JR

Those 5 ticks, sound like the TB is going directly into ice break mode. When you start, the TB closes off quickly to find (relearn) minimum closing position, if it binds or there is too much friction (slow moving blade) the EMC will interpret that as ice and it will try to break it off by closing hard a few consecutive times (the ticks) if on the last time it still feels like binding or too slow, it will throw a code and likely not to allow starting or normal driving.
