If so, all you need is the 3 inch one since the 2.85 will overspin it xD

I replaced the stock 8psi pulley with the 9psi on the serpentine side. I haven't replaced any others.

Technically just the 9psi pulley alone slightly overspins the head unit unless you upgrade bearings.

Gotcha. Didn't know that.
Ugh. Gotta wait til next year before I upgrade that

Would you guys mind sending me some of your data snippets that you send off to be used for tuning? I have an anomaly where one MAF (bank 1) is reading almost a volt lower than the other at times and I wanted to see if anyone else's car was doing the same. Thanks!

I'm at turtle64b@aol.com

EDIT: To follow up on this, it seems that there is not equal flow through the intake Y-pipe.

Swapping MAFs gave the same anomaly on bank 1, swapping the connection moved the anomaly to bank 2, and swapping the MAF while still connected to the same harness also moved the anomaly to the other bank. This means that at idle and light-medium acceleration, air flow through the two branches of intake Y, in my case, are significantly different. Since the Y pipe meets again in the manifold and the air mixes, the bank associated with the MAF that has the anomaly is getting much more air than sensed by its associated MAF and the other bank is getting less. This would explain my lean condition as well as the sometimes very rich condition that happens at idle.

Is anyone else experiencing this? If you look at your datalogs, it looks like one MAF reading out much lower than the other one. This can be dangerous for the engine as one bank will run rich and the other bank will run lean, potentially dangerously.

Have you replaced the Stillen extension cables with the later version? The original cables are a known problem.

Yessir!

Quoting turtle's message so it doesn't get forgotten, but is anybody using the innovate ECB gauge complete kit? ECB-1 (BOOST) Ethanol Content & Air/Fuel Ratio Gauge It comes with gauge (fuel temp, boost, ethanol content, O2). Complete kit also comes with MAP sensor and ethanol sensor. Is this everything I need or do I assume I still need a Zeitronix ECA2 Ethanol analyzer?--and anything else I'm forgetting in regards to gauges and flex fuel needs (aside from actual fuel system). Any reviews or suggestions for my gauges?

I'm running the complete kit. I believe the only extra pieces I needed were the fittings for the flex fuel sensor.

I appreciate you! My post can fade in to the dark. I got a full speed density tune from Seb last night, flashed it this afternoon, and it's a night and day difference! Talking to him, some cars get equal flow and some don't. For those that don't have equal flow, some can be tuned for, and some can't haha. I plan to work with him on full SD unless I figure out some way to equalize flow. Thank you guys!

ANMVQ · 03-29-2018, 11:04 AM

^^^ He'll for sure straiten things out he's a very good tuner

brucelidat · 03-29-2018, 12:43 PM

Ordered the kit through Seb, install probably in May/June. Can't wait.

I also have this same issue ....Accoring to Seb there’s not much we can do about it as this is a result of the Y-Pipe design. It’s not a big significant difference between the banks but voltage on both banks will never come out even/identical. Since ur tuning with Seb ur in good hands.

Changed my filter set up today make life easy when changing the filter etc.
I had to open the area of the stock intake up a bit but all in all happy with the results
I'm not chasing every last bit of power so I happy with a little restriction but in all honesty car feels the same but back on the dyno soon for a bit more tuning

I did a similar setup a while ago. Definitely felt a significant loss of power. Got any more info on that silicone coupler off the SC?

Jayhovah · 03-31-2018, 10:47 PM

So I've had two stupid ideas tonight about adjusting the intake setup on this kit...

Stupid idea #1 - could you fab up an airbox/manifold to mate to the front of the SC and then pipe that to a filter in the bumper? Still would deal with a 90 degree barrier in flow but at least you'd have more cross sectional area in the path?

Stupid idea #2 - use one of those rock-screen setups on the SC and then add a filter before the IC (or farther downstream before the TB's)? Can't think of a reason why the filter couldn't be pressurized..

I have been drinking.
