I just bought my Evo and I have never tuned so I need some help. I do not have a cable or anything to tune with yet. I have a buddy who is supposed to be setting a laptop up for me, but it is not done yet. My car runs very rich on startup and misses for a few sec.s if you don't let it warm up for a minute. I want someone who is experienced and willing to teach me.

I live right inbetween cincy and columbus. My car also idles low, then it will idle up to about 1100-1200. It has a set of 272's and I am new to the cam game so maybe this is normal. I basically want the help beause I don't have the stuff needed yet and I do not want to destroy my new cars motor because I am dumb when it comes to this. Thanks.

 

this might help you.... it is a start.

what kind of evo

 

As long as you can understand all the parameters and measures as well as what's on the car so that you appropriately have the mod input for the tune and know what will cause what to happen where in the tune....you'll be fine. If you don't understand latencies, dead time, scaling, maf voltage input, knock feedback....don't blow it up. What I listed is nothing compared to what you will get when you open up your file via RR, Open ECU or whatever you are tuning with.

There is a reason why people pay for tuning, some get it and some don't. This is all teachable and available to learn but try it not on your evo. Try it on something simpler. A boosted car (that costs in access of 12K or whatever you bought it for) is not worth your next few paychecks for a motor due to a hiccup in a tune that with proper supervision could have been avoided.

There are people who offer tuning classes, remember that every tuner is different and like to tune different ways with timing control, boost or even trims.

The first statements were only for you to deter from doing it yourself and being patient on finding that sort of help.

Also, 99% of the time, that sort of intellectual property costs money, but this way you can do it yourself later. If you have to time, take a course in thermal dynamics and kinetics at your local college, this will be the best first step you will ever have taken into tuning your car and understanding the basics.

Some tuning course that I've seen have taken up to 8 hours with only a few participants being able to get onto the Dyno and self tune the car. Knowledge is key and don't forget that. Some people on here will tell you that they've hopped into a car and started tuning, sure...some have that ability. Others have gotten away with the fact that the Evo's safety features like pulling timing or compensation for fuel trims under knock. Sooo, it can go either way.

 

It is an 03 8, I added my sig. sorry forgot to do that before hand.

I basically just want help fixing the idle and someone who knows how to tune to give me a basic rundown, so I can see it being done. I learn better hands on than reading. Reading how to do something without seeing it being done is useless to me. I see it being done I can learn it fast. The car has been dyno tuned but IMO they did a terrible job on setting the idle. The car jumps around to much and almost dies at stops, athough it did die once on me just awhile ago. If someone is close I will pay a little for the help and feed them. .

The car has a o2 sensor gauge but I have not looked to see if it is a wideband or spliced into the factory o2 narrowband. The needle bounces around an awful lot and I don't know how steady a wideband is.

 

dieing at stops happens to alloooot of evos on this forum.. i'd suggest readint threw those threads to see what they tried and what worked and didn't work.

most also set the idle when you have cams to 7 - 10 degrees at 1000 and below rpms...(or whatever your idle is set to).

also raising your idle a bit in the software helps too...

nothing is really written in code you have to decypher in ecuflash, so you can pretty much search any lingo in ecuflash and get a hit in the forums. also in the ecu flash threads should be a sticky of how to tune.

however if your car is already tuned and you just want to mess with idle, try setting the ignition timing to 10 degrees ... or it could also be fuel trim related...which there is a thread on that as well. but prepare to get your reading glasses out.

 

My problem with the idle is definately fuel, it will black smoke a little and the AFR gauge will peg itself below 10.0-1 AFR, then shoot back to stoich range then back to rich constantly. This is what I am wanting someone to fix for me until I save up the money to buy all the tuning stuff needed. I can learn better by being walked through it than reading it, but I have been reading all day on the tuning methods posting above. I am taking a break on reading it today, I got down to the fuel tables section, lots of reading.

I finally got to take the car on a long drive today to work which is one hour each way and I love how the car cruises along nice and smooth. Love the car so far, I normally drive an almighty super scort zx2.

Thanks guys.
