OFT - Guide To Dialling In Your OTS Base Tune

[oldgunfan]

I was trying to change my load limit table like Wayno shows but my table only goes to 3200 Wayno's goes to 4400. I'm using the OFT C series def's. One other thing Wayno shows load limit table B, Do you change table A too? I'm sure I'm overlooking something.

Copy and paste both tables.

You can edit the axis, not just the values.

Sorry had to go to outatown just got back. Thank you Wayno and JB86'd. I just got a open flash header and I'm going to put it on this weekend, Ill flash the tune then. thanks again.

Well I know I don't have enough time (10 miles) on the tune but I noticed my AFR was in the high 11's during a 3rd and 4th gear pull. I don't know if it's anything to worry about but cruising it looks ok. take a look and see what you experts think. http://datazap.me/u/oldgunfan/stg2ue...-2-3-4-5-6-7-9

Your pulls are richer than your O2 sensor can measure. Probably not an issue, rich is usually safe just less performant. Trims there are at 0% right now, so it should even out if you give it time to learn.

I could use some help in dialing in the load limits. My car has an EL 4-1 catted header and apparently, none of the load limits on the first post fit perfectly. Below is the most recent log and the current load limit is attached:
http://datazap.me/u/akyp/20160126-st...4&zoom=825-961

Notice the rich lumps at 2800 and 3200 rpm, then the lean lump at 3800. If I'm understanding it correctly, the rich lumps can be fixed by lowering the load limit which I've been slowly doing. However, raising the load limit at 3800 rpm probably won't help the lean lump, as it's already at 1.10, but the recorded engine load at that point is just 1.06.

Should I think about messing with the MAF scale or just use another scale (I'm currently using one of the scales from Wayno's ROMs but forgot which one)? Or am I doing it completely wrong?

Ok I got about 500 miles on my last flash, ver2.7 stage2 UEL 93oct tune with Wayno's load limit and fan mod. I just did a 3rd gear pull it looks fat like 11.7 to 12.3 afr. any help.http://datazap.me/u/oldgunfan/log-14...0&data=1-2-3-9

Hello sir wayno, been reading this topic for a while and i tried maf scaling my rom. But i noticed that my cal id A01J and definition which is RR_ZA1JA01J doesnt have Load limit maximum (RPM) tables , is it possible to still do these maf scaling?and do you possibly have a definition for this cal id?

you dont need those tables for maf scaling

you only need to alter the MAF scale table flow numbers

if you redownload the romraider def tdd has updated it for your calid to include those tables

how much should I lower the MAF scale?

It's not really that off..you should log commanded AFR. On the stage 2 tune it looks for around 11.75 AFR towards upper rpm and WOT. I'd leave as is for safety margin, that's me though. Going slightly leaner wont buy you much.

Steve, i had checked it again and it is indeed updated. thanks to you and Td-d. That link you gave me should only be used on my stock map and not the OFT map , am i right? (it can load and open up both stock and oft rom on romraider using td-d's def. But Im not sure if that def you gave me was intended for my stock map or for the OFT map. Since OFT_def cannot be used on stock map, im thinking that def on the link (Td-d) you gave me was intended for my stock rom (ori) only ) ?.

@Wayno, I'm trying to adjust my Base Timing B table to reduce knock, and I noticed something. When I first start logging my tune the knock is higher, and reduces the IAM more, than after I've brought IAM back to 1 and started pushing it again the knock isn't as much and the IAM also doesn't go down so low. This makes me feel that my car is learning and mapping knock on some kind of table in the ECU, and if I could only download that table I'd have the perfect map of where knock is happening, without having to log, read, re-tune, and log again. Do you think it is possible to download this table with a tactrix cable or something.
