We get ethanol over here, but only in 10% concentrations so we have not had to spend any major efforts into custom tuning for it.

The fan controls could have been wrong. As I originally posted, my rom used the 3 column table and while I was looking around saw the 9 column table in the evo 9. Both use the same temperature scale, and both look the same, and not having another car at the time to check I just posted it up for others to test. Later searching showed the 3 column maps to be in the other roms too so I would be playing with that map first for fan control.

675e should get you out of trouble for the Load scale.

 

Disabling that ignition table definitely had an effect; the car basically ran like garbage while idling/warming up (unresponsive throttle, stumbling, etc). At some point when I have more time, I may play around a bit with this.

It didn't help with cranking start, though, which got me thinking: none of these tables are going to have much of an effect on the act of actually starting the car, will they?

I wonder if advancing the exhaust timing a few degrees wouldn't help a bit (not exactly the high-performance choice, but perhaps more appropriate to an ethanol-based fuel). Too bad I don't have adjustable cam gears to try this out...

But at this point, I should probably move this to the alternative fuels forum, since it doesn't have much to do with the new maps discussion.

 

Do you mean the warm up timing trim tables? I disabled the warmup trim setting periphery0 bit9 = 0 and found that the car ran better when cold (temps currently are 50-60s in the morning).

 

Hey, has anyone confirmed any of the maps yet? Thermo Fans? Ignition Trims? Anyone played with the Decel Delays for the cars with throttle hang problems?

Where's the feedback???

 

I don't understand much of the code-end of this so I don't know what you mean by 675e. Are you suggesting I replace the "Scaling = "Load"" with "Scaling = "675e"" ?

 

using bit9 to disable the coldstart works fine.

the ONLY problem is sometimes the idle will rev upto 2k in a cold cold morning...

 

Yeah that's what mine does as well.....starts at 1500 cold idle then after I start to drive and stop again the cold idle sits at 2000. Small price to pay for the car running 99.9% better on a cold motor

 

yeah i'm not fused either way.. car warms up pretty damn quick... good for really cold climates thou not so bad in AU

 

What is the current temp there Tephra? I am heading your way in a few weeks for work.

Sorry for the off-topic, can't pm Teph.

 

I can't test anything at the moment, as my car is dead

 

No, the 3D table and 2D control table that Mattjin and I were discussing a few posts up for 96530006. I changed all of the 255 values to 0 for the control table, and noticed a lot of bucking and sputtering at startup as a result. I didn't have much time to spend looking into it more, however. When temps get back down again, I'll give this a try, it sounds like a perfectly acceptable solution.

Interestingly, the 2000 RPM idle problem is something I noticed when I was in central Canada a few weeks ago running on 91 octane again. This is on 96530006 (on a car originally equipped with 96940011), with periphery0-bit9 set to 1 (default). Weird.

 

Mine does that too.

Another thing: I swear that the car idles better now when warmed up. There's no reason why it should, because the code shouldn't affect idle. Maybe its the cooler daytime temperatures.

 

nah mine still idles rough - like an evo :P

Did u have a chance to look at by FAA bit10 discovery?

I will be doing some more road testing today so hopefully the car will feel like magic

 

?

 

Keep playing, you will figure it out.
