Surprised you would say that, since the "chipped" aspect of an ecu is the "tune"




So, basically what you are saying is ridiciulous, you are also saying you are supposed to do?



Chipped p28 is just loading a tune map onto a p28 ecu. The TUNE varies, and should be fine tuned to each individual chassis.

I'm under the assumption that when I see "Tune" I mean actual TUNING per-say, involving a Dyno and such, My apologies. I've almost ALWAYS had an S300 or several, I dislike the "CHIPPING" aspect of tuning or buying basemaps ect..

Guess I misunderstood.

Now that part I don't get.

Chasis effects weight, but if we're talking a stock motor here, how much fine tuning or Horsepower you expect to make to mitigate the hundreds of pounds difference in one chasis to another? It's gonna make the same power regardless chasis to chasis, 1-2HP doesn't accomidate a step up in weight class, retroactively it's equally non-beneficial.

Well, just as one of MANY examples I could give;



ECU mapping for a car in Texas will run like ASS if it is applied in say, Colorado.


Destination has a tremendous amount to do with IAT, atmospheric pressure, start up temps etc and a lot of those things dramtically affect the tune.


Compression in each engine will be different, slightly. Even if the compression ratio is the same, same stroke, etc etc. It will vary a few psi from engine to engine. So, AFR's will vary a bit, egt's will as well- and those things should be buttoned down.


and the list could go on and on and on.



"chipping" an ecu is just loading a map onto a chip, and then installing the chip in the ecu right? So, aren't you and I saying the same thing? But you are suggesting a custom basemap and go, and I am saying fine tune on a dyno to get your custom tune.


Same concept though, the "basemap" is the "tune" in your scenario. A basemap is generally far from ideal though for long term driving. 99/100 times, you could have the same basemap, on the same engine, with the same components, and there will still be minor differences when you play with everything and the BEST outcome will vary from motor to motor. It will.


I've probably tuned 50 DSM's in my life. Most of them had a 14b, a pull style hks BOV, 3" charge pipes and a FMIC. Nothing crazy, but duty cycle, enrichment(s), IAT settings, ideal ignition timing etc etc all vary quite a bit.


Same stroke length, same bore, same compression piston, same size valves, the thing is, all motors are different. They are. No two are identical, and no two performance tunes will be identical, even if the drivetrains share the same components.


Look at tuning information available for the s2000, another great example of varying results with the exact same drivetrain. Some engines just react different than others, for a wide variety of reasons. Running a custom map, you need to spend some time on a dyno with controlled ambient temp's to get everything ironed out correctly. Otherwise as you tune, you re-work the same shit over and over because its never the same temp the next time you tune, its never the same atmospheric pressure, etc etc. Tuning in a controlled enviornment allows you to rule out some of the variables and get the best overall tune.


Now, I'll admit that the outcome may be minor as far as differences go. But how smooth power is delivered, how smooth you rev the engine, AFR's, egt's etc etc will all vary quite a bit until you get your tune buttoned down on a dyno.

Ok, again now in THIS case, altitude, location ect ect...granted, I get you. In full. I agree and understand. Location, especially between two different elevation levels, makes all the sense in the world.

Here's mine...



Valve cover's not mine, had to borrow for the startup and timing...

[Jarrett]

It looks OEM. I like it.

[drummersteve7]

well since the h23 vtec came out of an accord sport wagon.
it makes since you can put it in a wagon.

Also in support of is a wagon worth doing? F22B-DOHC-T

YES, it is!

Next question about tuning, H22 runs a H23 VTEC like crap.
I street tuned mine, but started with the H22 map.
And it runs great, has been that way for 2+years.
Other people have purchased my TUNE, and ran their cars just great.
No complaints as of yet on anything I have tuned. (Except my own boost, lol) That's why I don't tune anyone elses turbo car.

Here is my do it in a day H23 VTEC swap, needed it done quick!

Damm Winston that's clean man . I've been watching all your vids great work man
