Any chance you'll have a stock GT4 at the track with you? I loved Sharkwerks old Kermit video when they ran their 3.9 vs the stock GT3 to show the true difference in their mod. It would be great to see the delta your setup is making vs stock this way.

 

We'll do that with some local customers once the production parts are released. Ideally we have them all on same tires, same suspension setups, and similar drivers, otherwise the test isn't so helpful...

 

Production prototype headers to get finished up this week, then jigs, mfg bends , then pricing and group buy!

 

Hey Jaime,

Status on CEL with NO tune test?

 

Thanks Jamie. Sounds like I should be able to get a set on for the Fall Smokies.

 

No CEL with stock tune...

I didn't say everything the right way. It will still be cutting it close but we'll do our best!

Jamie

 

Thanks.

 

How is it not triggering a CEL long term?

 

Similar way to our 996,997 and 991 GT3 systems. The newest RS gave us some curve ***** but have it resolved as well

 

I thought I remembered reading that some of your GT3 system cars were eventually triggering CELs and you were not guaranteeing no CELs on stock tunes. Have those all been resolved and now they are guaranteed no CEL?

 

The only way to guarantee no CEL is a catted system or a tune. We have been running a new post cat O2 solution for the bit more complex protocols. We have it being beta tested by a few folks that had some more consistent CEL on the RS and a GT3. So far it has been working great. The interesting thing is it car to car dependent, some cars are more sensitive than others. We have solutions for the more sensitive cars now. For the GT4 the question was if we had CEL on the stock tune and so far we haven't. Does that mean there will never be, can't say until we get some more time on it.

For those that want no tune and absolutely no CEL, a catted system is the answer. For those that are OK with a tune, solution is easy.

 

Manufacturing prototypes getting put together today/tomorrow and testing a few more ideas Charles had. Also Cobb is getting a couple of the map additions we requested put in, just need a few more. I know Mitch is on it, so should be exciting!

 

Hi Guys,

Here's the production prototype in the jig! Will be able to submit RFQ for the 321 mandrel bends on monday. As soon as I have the details we'll get the group buy pricing up and start a new thread with the dyno info, tune info and Pricing/leadtimes!
