Thread: nemuSA tune needed! det block,ve head, n62, id1000 (3bar), e85

det block, ve head, n62, id1000 (3bar), e85 tune needed.

I will tell you from experience, with E85 just decrease the fuel injector size by 30% and that will make it "safe". However with E85 I highly recommend a professional tune as ethanol ratings can be iffy at the pump and timing is where you get your power. Play it safe.

My tune prior to the e85 setup was jacked. I want to start with a fresh base tune

Not 1 person.....!?!?

I loaded a base sr20de TCD, changed the injector size (RC1000), changed to MAP (GM), then set my idle afrs and cruising afr's. Then when I was comfortable I decreased the fuel injector size by 30% and filled my tank with E85. That is literally all I did, then I drove it to the tuner for a professional tune where it put down 330hp at 14 psi on an 18g turbo. You do not butt dyno E85. Its sole purpose is to squeeze as much timing out of the engine as possible while using a pump gas. If that is not your goal, then E85 is not for you. I do not mean to sound harsh, but it is worth it in the long run to heed my advice.

The NismotronicSA is so forgiving it is ridiculous, but you must ensure your electrical system is working properly, ie all your sensors are within parameters. This will cause more headaches than anything. Chances are your previous tune was crap because you had some bad sensor readings.

If you want to post a log and your TCD, I would be more than happy to look it over.

on that tune. what was your ending values for your injector size section? what was your BASE, CURRENT, and ALTERNATE?

Base: 259 Current: 700 Alternate: 588 It really was that simple. It took some smoothing out due to the larger injectors and cams, but I was idling around 1000rpm. Maybe @eggman will be so kind and upload the E85 tune from his NX, my old one I spoke of.

My alternate was just my "Oh shit" map.

pls close thread.
