On a question on BLM Table. If the BLM is 89, what does that represent? Does that mean that in corresponding AFR table, for RPM and TPS, I am using 89% of that AFR ratio, which to me means it is running slightly rich? Or/Does it instead relate to the AFR/Alpha N Table?
Another IAC issue today, or should I say keep fixing it until it is broke.

Not that bad but wanted/needed to check and reset my IAC as it appeared to be running high, 35-42, consistent in the logs. Also wanted to Sea Foam the TB and look for black smoke and mainly to clean the plate and make sure it was working smoothly. Well the Doherty funnel insert, TB/plate, and inside body was dirty. Seems I need to oil the filter more or something.

Sea Foam Works!!!!! Followed directions, warmed it, easy as I was checking IAC, Held open the plate, scrub with old tooth brush, wash more down, let sit 5 minuets, fire it up, and they DO mean an open Area, and man what a sight. Mostly all white and did not look like a lot of carbon but smoke she did.
Shut it down let it cool and fired it up and no smoke and all seemed well put about 20 on it tonight no smoke and all seems well there.

GRRRRRRRRR IAC

Set it, ran it 3 times from cool to warm 96C or so and DEAD NUTS on 32 bouncing to 35 but staying at 32-32 consistent. It was cool here in PA and I was using two box fans to cool it as it heated up to 96-110C or so. I watched Live View THREE times and when the Cold changed to Warm Engine in the little window of Live View I was at 32 or so all three times and watched it, dead on the laptop on a chair at eye level. Even went as far on the last two to put the filter and end cap on the Doherty as I had once suspected the difference of the air ram of the Doherty, and nothing else, would change when a filter and the end cap is installed, nope all three times as I said above.

Ran 2 logs tonight and WTF, log showing IAC at 25-27


It takes FOREVER for it to reach 96C. DO I have to wait it of for the 160 sec setting to expire before I can ride? Will it set on a longer ride?

I will say I am on the base 95 map, only 20-25 miles, no front trim done yet have the rear cylinder offset to -1, dropped advance in 2000-2500 by 1% and 2750 by .5% to help smooth the map.

Strange thing is it seems to run well even at this stage of starting over, but this IAC drives me INSANE.

Hey LAF, and all you other TCFI junkies!!
Your question on BLM at 89% means exactly what you think. According to the AFR you have set for that cell, you are running slightly rich as the BLM is telling you that to acheive the desired pulse width to attain the corresponding AFR, you need to reduce the fuel as all you need is 89% of what you are actually running. To correct to get to the desired fuel for that AFR, I'm sure that you know how to apply the BLM to get to 100% which means you are dead on balls, (at least for the calcs that the BLM has made for you up to that point).
To get to a desired 95% BLM the easiest way is to apply the BLM to the Alpha N to get to 100% and then add a small amount of fuel to the main fuel map and then LIVE VIEW to see where you are on BLM. I assume that you are trying to get the average BLM at idle mode down to around 95% to get good idle and are monitoring it Live View right after the bike gets out of the idle program and is warm enough to get into the main fuel tables. Once you get there then lock out the 0% throttle column to be eliminated from any future adjustments that you may make with the BLM tables. And just a hint, lock out the 2% TP also as this row does not calc the BLM or AFR correctly in most builds. Simply smooth them manually as the BLM is going to tell you to remove fuel from this area when, in fact, you may actually need more.
A sticky for the TCFI techheads....... Wow!! Let's have a poll to see who is the first one is that gets a one way ticket to the asylum from fugging with the TCFI too much.

All the best!
