Capability of ecu tuner in sgp

[Thumbs]

>>However, what are the steps to tune ignition timing? Possible to do this on the streets?<<

 

The only proper way to tune spark advance is to use a load-bearing dyno. Although you can tune to knock threshold using a knock sensor and dial in some trim, this is a only a "best guess" method since you wouldn't know the tractive effort of the engine at any given point in time.

Thanks for info.

I figure that advanced ignition + no knock does not imply improved output.

Well, it depends on how you look at it. If you are running a tuning business, you need to protect your map, so that others can

[Sheltie2306]

Sorry, technically can

First of all, you must build the fundamental of how combustion engine works, especially the characteristic of air fuel ratio, ignition timing, boosted engine (turbo, supercharged). These are usually very dry and boring, but just have to get through it and make sure you understand them well. There are plenty of academic books which give very systematic information. If not, go browse the web and organize yourself, also can. At the end of the day, you should understand the typical air fuel ratio (AFR) of NA and forced induction car. Bare in mind that the people are typically talking about red line, high load AFR, such as about 13.5 for NA car, 10.8-12.5 for turbo cars, etc, but for light load, we are still hitting for 14.7. For ignition time, get yourself to understand about the meaning of

I have no experience with e-manage, but just to share some experience. Yes, I also find timing tuning a challenge. What I can suggest, and also what I do myself, is to fine some way to capture the timing table of the original ecu to build the so call

Hi Sheltie2306,

 

I am impressed.

I do learn about how engine works from How Stuff Works web site. It gives a very simple but effective description of the mechanics of the engine. It even describe how honda VTEC works!

Thanks for the pointers... will read what you have advised.

[Sheltie2306]

Hey, talking about vtec, you should check out this site : http://www.hondata.com,

plenty of vtec information.

 

Check out specifically: http://www.hondata.com/techk-protraining.html

You can even download a series of "e-leaning" video, teaching you how to tune vtec engine. You need quite substantial pre requisite knowledge to really understand this, but if you do, its dam impressive. Vtec has a

anyone experienced with tuning drive by wire sytems(electronic throttle)..heard not many piggy bacl ecus can be used to tune this type of ECU

[Zrun]

Drive by wire.. I'm not sure how much different it is, I think it does not have TPS sensor, because TP is controlled by the ECU directly.

 

Technically, nothing is impossible, maybe you need to convert the throttle position duty cycle into TPS-like signal. Which is minor hack.

[Zrun]

Are there any gains by tuning ignition for higher octane gas for NA?

 

For FI, it is required to go higher due to the more stable nature under boost. But for NA, I heard that there's not much purpose to go higher octane, even if you tune it aggressively.

[Sazali]

so who are the reputable tuners in SIngapore?

[Sheltie2306]

Yes, agree. For NA, higher octane will allow you to run more aggressive ignition timing, but my experience is hardly noticeable with another few degree of timing advance.

Do you tune Unichip.Need tuning after the mode.

[Vtim]

Bro, Sheltie2306 is no holidaying with his wife in china lar! He'll be back end of April or 1st week of May to answer your question

[Roy669]

Roger!thanks Bro!

[Vtim]

no prob, he's actually my colleague

[Sheltie2306]

Unichip can only tuned by authorised dealer
