ECU tuning...

[SuperTuner12010]

I searched, found a few stickies but not the one I was looking for. I had read a stickied post about the different variations to use; cheap ways, expensice ways, and all kinds of different information on it. I couldnt find it thougg...

I have a lot of questions...Im going with an H22. And I want to runa chiped p28 but I have no idea how to chip and what not. Crome has p28 support right. I know you can download crome from their website, but what chip do you use to chip the ecu and how does it connect to a lap top?

This is what I used to get myself started
Clicjk here! It's a good start to DIY chipping and what you need to get yourself started. Save a copy to your desktop it will come in handy

There is also this site: Click here for another good tute on Getting started with Crome.

Crome and Uberdata are all chips that have to be burned right? I want a system that you can hook a computer up to the ecu.

Hondata s300 can do this right?

And I know using a dyno to tune is a lo9t better but for those wwo tune without a dyno what exactly do you tune and what do you base it on?

[GhostAccord]

Crome and Uberdata are ROM editing applications (software) That is used to compile a data file or Bin file that is burnt to a chip.

Crome, eCtune, Neptune and Hondata all hook up to your ECU via a computer. I think what your looking for is called RTP or real time programming. Yes Hondata and Neptune can do this but with a product such as the Moates Ostrich so can Crome and eCtune. Uberdata is going the way of the dinosaur as far as I know.

You tune from basemaps. These consist of fuel and ignition maps along with controls for all of the other PGM-FI sensors and outputs. To tune on a dyno or on the street most people base there map tuning on Air to fuel ratios aka AFR's. The afr's are monitored using a wideband O2 sensor (Innovate LC-1) and some tuners may use EGT's or exhaust gas temperature probes as well.

Sorry I am not a professional tuner and I don't have all of the answers for you. but with what I have given you, you should be able to do a bit more research on your own into what AFR's, Basemaps, Wideband O2 sensor and EGT's are all about. That is how I learned, lots of reading then hands on.

There are a few books on modern engine tuning and performance. "Building & Tuning High-Performance Electronic Fuel Injection" is a well known tuning book by Ben Strader. There is also a $400 EFI 101 course that you can take @ EFI University if your lucky enough to live near one of the lecture sites.

I vote for Ghost Accord to be ECU tuning mod.

[SuperTuner12010]

Thanks alot a lot of good info...I plan on getting a wideband o2 and trying to attempt a street tune.

[TheChosenOne]

Great info!

So, without a dyno, and lets just say someone knew how to use chrome or Uberdata to their full potential, could the tune be precise enough to properly run a built/semi-built motor?

Well said.

Lol only cause your sick of everyone Pm'ing you

Also there is now Haltech ecu thanks to Chessboxer (free plug )

yes.

[GhostAccord]

lol...yeah Thanks for the nomination but I don't have the time. Nor do I have the knowledge & experience that you have d112crzy..thanks for the props though.

As for your question about street tuning......tuning without a dyno. I agree with d112crzy. Only thing is it will probably take you longer to hit all of the points on the graph. On a dyno you can control the amount of load on the engine at any given RPM to help you get a "quick" and precise tune.

Street tuning in my case was like this. Drive & log - interpret log - make changes, Drive & log - interpret log - make changes, Drive & log - interpret log - make changes etc etc. And you have to find a good road to get all the different load variables. ie a nice long even grade hill, a long flat road. Staying within the confines of your local speed limits of course I did mine over a two day period. It's just faster on a dyno.

[d112crzy]

but not all dynos are load dynos.

Stop watching fast and the furious and start reading.

[GhostAccord]

There is some inexperience shining through for ya, only dyno I've been near was a sustained-load chassis dyno. I just assumed they were all like that....never realized that there are dynos that are acceleration "calculating" dynos.....learn something new every day.

[98vtec]

just buy a chipped ecu. I will only chip an ecu for someone who begs me. I hate desoldering as i dont have a 100 dollar desoldering gun with a built in vacuum pump.

eCtune and NepTune are the only systems i support now. Crome software support is god awful, uberdata is out dated, Hondata can suck a nut, and standalone is freaking expensive, lol.

[chessboxer]

Tuning a Haltech E8 is actually pretty easy, very user friendly.
/shameless plug!

But you are right, stand alones are not cheap, but there is a reason for that too. Not for everyone by any means, but they are great for those who can justify them.
