Hmm, look like it would work pretty well the same at half the price. I'm a bit leery since the seller has relatively little feedback. I want to trust your review, but your only posts on this board have been from this thread regarding this product.

I need to clean it up but it shows the basics of whats involved. . I should probably run it through flex sleeve to give it a more factor look. You have an additional fuel injection harness, a flex fuel sensor, and a temperature sensor. Believe me the engine bay looked far worse when I picked it up from Copart

I wasn't referring to what you did with it, it's just a birds nest of wiring to deal with for that kit

Looks pretty much the same for both of the kits in question. I guess it's just the nature of the beast with this ECU. I'm sure it could all be tucked under the plastic coil covers and look decent enough.

true but some of us don't run the fuel rail covers and no way would I want that visible... if you wanted to spend the time you could probably run it under the intake or behind the manifold so it's less obtrusive but whether that's worth the effort depends on the person

Any add-on kit that does not include injectors with increased flow capacity is playing with fire, as 100% E85 requires substantially more fuel delivery than your standard gasoline (E10), which a vehicle's stock fuel system is likely not going to be able to supply while keeping injector duty cycle reasonable.
Stoichiometric ratio is much lower for E85.
(I ran my 2001 Corvette Z06 on E85 with bigger injectors and a tune back in 2008-2010.)

They recommend the system to be used on a stockist motor. I'm on stock 2001 injectors currently making well over 400whp. I'm getting the car tuned for 60# injectors soon, then I might try one of these out .

Let's see your Scan and check out your IDC at 100% load above 5000 rpms.

if you knew what you were talking about you wouldn't say 100 percent E85, you would say E100.


My stock z06 ran e85 on stock injectors and stock pump.

What do you think E85 means?

It means 85% ethanol
15% gasoline

And I'm sure your car "ran."
That 120% IDC though!

I just said I'm getting 60# injectors put in for that exact reason. That's nearly 3x more than what's currently in there. E85 takes 30% more fuel. Should be plenty of head room.

You'll be fine. I made 481 rwhp NA on corn with 50lbs injectors. Dont remember what the duty cycle was at though.

what's "That 120% IDC though!"? Is that millennial for " I'm sure your injector duty cycle was at 120 percent." ?

Just wondering, how many cars or trucks have you tuned on ethanol?
