Trying to help a fellow Evo'er out who has a X. Are we removing the o2 sensor from the test pipe and the wire harness? Completely taking it out and putting it in the garage, so to speak ? or is it just tied up under the car ? Sorry, I'm confused a little, as usual.

This appears to be a AFR calibration map:

Code:

	<table name="Calibration Fuel Map" category="Misc" address="576d3" type="3D" swapxy="true" scaling="Percent128">
		<table name="Load" address="617d6" type="X Axis" elements="41" scaling="Load"/>
		<table name="RPM" address="617aa" type="Y Axis" elements="19" scaling="RPM"/>
	</table>

I have noticed that 52680017 -> 52680020 are different...

I plan on testing this map out (the XML is for 5268xxxx) in coming weeks, but I think its basically an AFR calibration/compensation map...

Interesting that they don't do it with MAF calibration. Do you know where this sits in the line of subroutines that determine the fuel pulse width? I'm kinda interested in whether its before or after the MAP compensation.

Not sure - it gets pulled together will all the other compensations...

Also if you dont have percent128 scaling just use AFR...

Just want to confirm that the O2 sensor disable works like a charm.

Thanks a bunch!

Now, if you can figure out TPMS warning disable, I'd definitely owe you a chocolate bear and a wish.

Thanks everyone for all their efforts into the X. Not only do I get to tune my car, I get to learn a lot and have fun while doing it.

Ok, maybe I confirmed too early? After nearly 700 KMs, I got a CEL...

I changed ECU Options #2, second last bit (bit.1) to 0. I removed the sensor from the exhaust stream and capped and covered it. I didn't remove it completely (simply because I don't know how

), could that have resulted in the P0140? I'd prefer to have to tied up under the car so that I can throw it back in if necessary, but if the only solution is to remove it, let me know.

Thanks in advance...

has there been any progress on the MAF scaling tables for the Evo 10? Just wondering because I need to adjust for my AGP CAI.

Intakes on the Evo X make your trims go positive beyond +/-5%. In the absence of the MAF table, You can bring them back into check by adjusting the injector latency. There is more than one way to skin a cat

so would adjust the latency by 5%. So change it from 532 to 558.

I am running the gunzo maps which should be about 11.8 afr in wot, but I am hitting 12.3. and I know it is unsafe I went back to the stock map when I saw this on my wideband.

Quote:

Choose an injector scaling
Log trims at idle and cruise. Trims change every 4 minutes, so you will have to log till the trims a stable at a number.
If trims are roughly the same, but positive, then you need to lower your injector scaling number.
If both trims are roughly the same, but negative, then you need to raise your injector scaling number.
If both trims are roughly the same but positive, then add latency.
If both trims are roughly the same but negative, then subtract the latency.
Changing the latency by 0.1ms will affect the idle trim by 10%. It will affect the cruise trim by about half of that.
If idle trim is more positive than cruise trim, then you need to increase the latency value.
If the idle trim is less positive than the cruise trim, you need to decrease the latency value.
If a car is running richer than it should be, then the fuel trims will become negative. Example: If a car is running 5% richer, then the LTFT will become -5% over time.

I have a question about the idle tables in ECUflash. There are 14 of them. There seems to be too many. Are these accurate? If not, then what is the code for the accurate ones?

Quick ecuflash question.

I don't have a pc, only a macbook for my laptop. Does anyone know if I'll have any problems running parallells, (the mac software that allows you to run windows on it,) with xp to run ecuflash for my X?

Thanks,

-Ben
