If you look at Christian's disassembly, you will see a handy subroutine at DDB7 that will only turn the compressor on once the rpm's have reached 438 rpm. Its...
Hi, I have been playing around with mapping a 2.4 stroker Evo and have some questions, specifically about how the ECU reads load. I am asking here as there is...
In my listing file .LST this subroutine is at DCB7. I thing better way to turn off AC is to use subroutine for AT that turns off AC if TPS is higher then 82% -...
I started logging w/ mmcd b/c of the ability to log wideband AFR through EGR T input, but I can't get mmcd tools to export the AFR to excel. The spreadsheet...
Hi Marcus! I have the same problem with my 2.3L stroker (CR 8.5). Jeff wrote this in message #6630: "..increasing the MAS SCALER at 549A, to force the the ECU...
The MAS Scaler is not used in the pulsewidth calculations. It is only used to scale the AFR and timing maps. So, the only reason raising the scaler value would...
That's some very useful information to know. Just to ocnfirm then,by reducing the MAF scalar I should be able to fall back to the load cells I would operate at...
Yes, reducing the scaler value by 15-20% will have a direct affect on how quickly the ECU moves up through the maps. I would suggest some caution though at...
Jeff, I have a stroker (2.3L) with CR 8.5:1. I implemented the 2G timing map cause of the same CR by your advice. Should I REDUCE the MAF Scaler, to match load...
Is there any point to modding the closed loop so that it cycles around a lower point than stock (i.e. leaner)? I understand that each O2 sensor is different so...
Have a problem at the moment with my Evo 1 and using a modified EA24b bin file with an Ostrich and Tunerpro RT. My problem is doing 1/4 mile runs. I launch...
You're making me think about discussions people have had regarding miscounting of air on shifts due to accidental metering of air flowing OUT of the air meter...
... Running leaner comes at another cost - you produce more NOx, and your cat might not be able to handle it. The normal feedback point is set for the...
Carl - Interesting thoughts, and I've not heard discussions like this. Forgive me for being dumb, but could you explain a little more: are you talking about a...
No, I'm talking about some of the compressed air in the intake system escaping out the mass air meter when the throttle gets shut. In other words, the system...
Ahhh, gotcha. It could be that I suppose. But how would I test for that and deal with it? ... EA24b ... If I do ... speed, it ... the gas ... gear ... is,...
Not sure, because I have no idea if that's actually the problem. I just thought I'd heard it discussed before that the code (at least in some cases)...
Jeff, No it's not your chip. It's a custom-made bin made from the Evo 2 bin. I am going to buy a swtich for the clutch and try to fit it up and see if it...
I believe Carl is talking about the 'airflow meter active filter reset' feature. It's used to temporarily ignore the maf readings when the throttle opening is...
Looks like it should work to me! 5 seconds may be a little long to do without A/C though. I use 90, which give you 3+ seconds before the compressor kicks back...
... OK, you use 3.6sec. I thought longer timer protects the compressor's clutch from "flapping", if rpm moves about 5k. How can I log, it works well? Why did...
If you want to really avoid "flapping" you could write a subroutine that would also look at the TPS, so the compressor will only get cut if both the rpm's are...
Jeff, did you see Message #6951? (I had a mistake: the jump back address "DD C7", not "DD C5".) Can it work? (If it works, I can combine the 5k rpm threshold...
I'd like to replace my unused solenoids with resistors to clean up the engine bay and keep the CEL off. Was wondering if anyone has done this before? Testing a...
http://pdf1.alldatasheet.com/datasheet- pdf/view/936/MITSUBISHI/M5269L.html It shouldn't be any problem, but that will have to be a rather heavy wattage...
