Anyone good at tuning?

[turbotalon1g]

well e85 is not idle friendly ... my car refuse's to idle on it ... but besides the point

speed density is not that hard to set up i believe dsmlink v3 has a auto tune function that is set up for base tune .. what dose your wide band say. That is your friend . Did you read the manual, it explains how speed density works and how to set it up .

www.ecmlink.com read the pdf on set up its painfull to read and understand but it can be explained

More horseshit information regarding: E85 and tuning.

I've had my car on link v2 idle link the bee's knee's on E85, old version 1600s and BC 280s.
You should probably take your car to a local shop and hope they don't turn you away for a tune.

but .. we for got one thing every Car no matter what is different.

You could have the same setup and one might run like crap one will run fine
its like saying every 1600cc injector flows the same .. my car idles good when im consistent at filling up at one specific pump when i change a gas stations car runs different cause the blend of 85 is different hence crap idle i have to change dead time to fix it ..

U are special so I'm done explaining. But to the op if u want a hand let me know.

You have issues then, and a finicky setup. Both my 1g & 2g both idle great on E85, and I can set the AFR leaner than most would dream of and still have a good idle.

Why would you use deadtime to tune ethanol percent? Deadtime is to tune to your specific injector, not fuel type or blend; that's what injector size compensation is for (besides for actual injector size and base fuel pressure). If ethanol % really is messing up your tune, it will change it at WOT too, not just idle. Deadtime has the largest effect at the lowest IPW's.

If you use closed loop like stock (I don't, I run open loop all the time), then it shouldn't even matter anyways as the ECU will correct it.

No doubt, over the last 4 years, I have had virtually every format of 4G6x (low, and high compression, 2.0, 2.1 standard rod, 2.1 long rod, 2.3, and 2.4) and they have all idled rock solid with 1600cc+ injectors dispensing E60-98 mixtures - no idle control, and a very archaic batch-file stand-alone...

As long as AFR's and timing was somewhat within expected values, it idled just fine.

YMMV

[turbotalon1g]

You guise R duummm, different cars will be different you know.

Tachyon, i'll have to pick your brains about some of your combos.

Did you ever get you car running boomdeez? I'm with tachyon and turbotalon1g, if your having problems getting your car to idle you probably have other issues like a boost leak, dirty injectors, leaky injector seals, bad fuel pressure or even to much FP since some people love to run E85 using the stock FPR? Once these engines are warmed up as long as everything is set correctly in link you should have no problem getting it to idle.

I am sorry I have not been responding as I was up at school and totally forgot I started this thread(3 different forums). I am still having issues and was just going to eat the bullet and see if DB could sort out the tuning. I am coming back this weekend to finish prepping the car for the dyno if you guys want to come by and see if you can help it out, your more than welcome to. Just shoot me a PM with your number and we will see if we can work something out.
