Innovate (Sprintex) Supercharger Owners Topic

Perhaps the people that said that didn't give me all the details however. I'd play it safe personally and put the tune on first.

At idle the car runs in closed loop and targets 14.7:1 AFR. This is the same whether stock or not. Even at low throttle the same is true. The ECU will just fuel trim as per any requirements. You could drive the car so long as you don't come out of closed loop on the OEM tune.

My battery died when I did my install. Jump started on the OEM tune. One advantage of not swapping the MAP sensor, as that would not start.

Well, I ran it. And nothing bad happened, lol.

It idled pretty low, but otherwise all seemed good.

I am trying to source a boot nipple for my sprintex 210. Am looking for the one that will fit in the back of the charger. I got the hex head plug out with no problem. Its a 5 mm. plug. Does anybody know where I can buy one. Thx Steve

Do you guys come across bad gas (car) often? Been struggling for about a month. Car has been pulling timing on every hard acceleration and even on average driving.
I've cross-referenced my old logs from when everything was dandy, and my AFR matches, my MAF matches, my calculated load matches, the oil temps match, EVERY PARAMETER IS EXACTLY THE SAME, and somehow my car is detecting knock.

I've gone into the engine bay to check for loose thingies making false positives, everything is locked in. I've gotten fuel from 2 different distributors, both "92" octane.

I refuel my car at 25% remaining every time. How long do you guys think it would take to clear the system of this bad gas? Is there an easy way to purge the tank entirely so I can start fresh?

I have refueled 3 times since initial bad tank

Thanks

@riboyster you're better off running the tank nearer empty otherwise you could be allowing a greater mix % of the poor fuel, which it does sound like. However by a few re-fills I'd have expected that one bad batch should have been mixed enough to a better blend. Maybe a seasonal change or some left in storage?

Are the ambient temps increasing? Could be higher post charge temps as the Sprintex is susceptible to it. You do mention that you're running an aggressive tune....

Higher ambients were my initial thought, so to eliminate that possibility I took it for a run earlier tonight at usual temps. I'm in the tropics, so I don't believe they have seasonal fuels. Doesn't get colder than 50F where I live. Car is tuned to run knock free at 85F, and I don't usually boost around above that.

Not too sure man. I think I will run the tank down lower this next time. I just recall having the problem resolve itself before at the next refuel.

You could purchase an onctane booster than mix it into the tank. I'd imagine that will help out with knock (depending on how bad the original tank of gas was, in terms of fuel octane).

I suspect something more than bad gas if you've refueled 3 times. Maybe pull battery negative terminal for 30 minutes and reattach to cause car to relearn tune?

Bought 5 bottles of booster last week, no effect. Reset ecu twice.

Anybody run oft with the 210 kit? Is it possible?

That won't help anything.

It's possible if you make a tune for it or get Shiv to.

When it closes it causes a surge of power as the supercharger goes into full boost, which resonate slightly in the drivetrain tension.
Also the valve will flutter if it closes while the motor is under a certain load. Its going to happen regardless of the tune.

So does this mean that if the parameters were changed regarding boost bypass that the charger could hit full boost much earlier in the rev range (say 3.5k for example?). Or, is this something that is not possible?

The bypass valve is not software controlled and is only operational when in vacuum.

You could superglue it closed I suppose. But I'm willing to bet money that you'd cook your SC and sprintex would definitely not cover that in warranty.

Also it already does hit full boost at any rpm. Your throttle just needs to be completely open.
