Do NOT use those plugs as they do not have a long enough reach use stock ILFR7H NGK's gapped down to prevent blowout. I'm at 22 right now as my car would blow out at higher RPM and peak boost with stock gaps. Denso IKH24 1 heat range colder and IKH22 is stock heat range plug.

Just trying to help and nothing against poster

 

Sorry, your absolutely right. I forgot the 9s use a different plug to earlier models.

 

I usually see 1˚ less than map at 85˚F IAT, and about dead-on 75˚F IAT and below. I also try to advance from behind MBT instead of before it for thermal reasons

 

No big turbo timing maps? On 93?

 

I have read this whole thread and have a question.

how come you guys dont rescale the load, starting at like 30 or 40 as it seems all the numbers 0-30 are the same.

also on rpm, why not drop the 500 and 11000 ands rescale?

my understanding is the ecu will use the last column or row if it goes off the table, is this correct?

I am building a map now and my idle is set at 1000 rpm so I dropped the 750 and 500 and the 11000 to get more res in the 2500 to 4000

and took out the 0-30 columns to get more res in the 260-320 loads.

will I run into issues on this?

Current mods are 272 cams (cossie), FPgreen, tbe, ams cooler, hardpipes running E50 (South african blend)

Mike,

I agree with you here, the only issue I have with it is you don't really know what else you are effecting when you change that scaling. I have succefully changed the load columns without any other issues coming up. However when I change the RPM scalings it seems to make my car, and others cars act "funny" in other areas.

For example, when I made the change in the RPM area my idle was all weird for a while, then my cold startup timing was off. Other tables that depend on those same values are now thrown off. Problems is we do not know EVERY single table and how it effects the ECU when you make those changes. I experienced weird problems so I went back to normal and everything went away.

The main point is that not EVERY single table is known in these cars yet and if you change that value what else are you changing.

However, I have successfully changed the last RPM point (11000) to a REV limit (8500 or whatever you rev to), and that seems to not have done anything.

Just my take on it, you do what you want, just thought I would share my experience, and possibly why others or tuners have not adopted this method.

I never change any scaling between 0-60 load since thats the majority of cruising and it may affect other tables we aren't aware of (and some that we ARE aware of). I generally never change RPM scaling between 0-3500 RPM for the same reason too.

 

Cool, thanks for the info guys, will rescale back to original.

what about things like your baseline WGDC? can you rescale these for better res at the area's needed or are you into the same problem as above?

Mike

 

BWGDC is definitely fair game to rescale.

 

I start mine at 3k rpm,scaled equally to redline.

 

Thanks
Mike

 

very similar in theme but not as smooth as JoT's
.

 

Any interesting mivec maps anyone cares to share?

 

There a MIVEC tuning thread, with a bunch of maps in it.

Sorry to go off topic but if you are down to 22 because of blowout then you would highly benefit with a cop. I am running Matts check my signature and I run .030 with copper plugs on my IX and it has no issues at all. As a matter of fact a local tuner using a IX with stock plugs that a guy brought in a IX misgapped at .045 didn't have blowout until 23psi so that gives you and idea how weak the stock ignition is.....just trying to help
