OFT - Example alternate maps for AT, 98RON, E85, MAF Scales

[MGPAX]

These Maps?

Nope. This one.
It just occurred to me that I might be looking at this table incorrectly. It's possible that the ECU uses it as a cross reference where it finds the RPM and goes across to the throttle plate opening it currently is using and then goes up to read the value that has been confusing me to use that somewhere else.

I'm guessing the true values are 0.01,0.02 ect. and it's being rounded down/up to display as is

Exactly this, I have set mine to 3 d.p. to view correctly.

Where is this setting?

Find the scaling of that table in the definition. It'll likely be 0.0, change it to 0.00 or 0.000. You can do this for anything you want if you think the standard settings don't work. Alternatively download my OFT defs and it's all done for you

I thought you meant a setting in Romraider. I didn't think of a variable declaration in the def.

Finally got an opportunity to post some of the datalogs from the past week showing the knock issues I've been having. Please check them out and send some suggestions my way on solutions and any potential engine popping risks.

Checked 02 Sensors and the MAF sensor's location in my GS intake, both are where they should be and tightened down. Could the header/exhaust cause this type of knock?

Much thanks Wanyo/Steve99,

PS: I'm seeing FLKC and MAF flux at the same time in log2. Also, 7-10% on LTFT so it is running rich as well. Ideas?

[Wayno]

People still don't know how fuel trims work, probably due to the focus on blind MAF scaling with tools. A LTFT value doesn't mean it's running rich. Having AFR far below target AFR when target AFR < 14.8 means it's running rich. End of story. Period. Full stop.

You shouldn't have that 2 deg FLKC at 4000 rpm. Do you have any part of your exhaust hitting bodywork at that rpm or any other noises then?

I've uploaded fuel maps that will rule out most knock due to running lean in CL.
- CL will run 0.25 leaner than OL, instead of between 0.5 to 1.0 leaner than OL. Before, when you switched from CL to OL, your AFR target could drop as much as 0.5 to 1.0.
- I don't know what side effects this can have on fuel trim learning, it should be nill.
- There may be a hit to economy.
- Once trims settle, it should feel smoother.
- There's some more fuel in the 0.8 g/rev column to deal with the knock there.

Just copy the 3 fuel maps out of it.

- Stg2 BPB 98RON map re-made.
- E85 now using petrol MAF scale as a base which is good for about +0.25 AFR in open loop.
- E85 has slightly modified MAF scale to lean up 3.2V and 4.06V by a further +0.25 AFR.

I.e.
3.2V = 69.5 (-1%)
3.44V = 87.74 (0%)
3.71V = 112.57 (0%)
3.91V = 134.75 (0%)
4.06V = 152.05 (-1%)
Before (OTS E85 scale - flat, but hitting 11.5 AFR at 7200rpm):

I'm currently running these values for my MAF. I haven't seen another car resemble mine though, even with the exact same hardware.

3.2V = 67.4 (-4%)
3.44V = 87.74 (0%)
3.71V = 110.3 (-2%)
3.91V = 131.8 (-2.2%)
4.06V = 150.2 (-2.2%)
Before (OTS E85 scale - 11.7 at 6000rpm, 12.06 at 6800):
http://datazap.me/u/wayne/206-stg2-u...zoom=1249-1419
After (OTS PETROL scale - 12.5 down to 12.06 at 7200rpm):

Just wanted to check if you have the latest tunes for A01I? I could not find the zip file for the updated changes. I am running a GTS Auto Trans.

My setup as of Yesterday is the following.

Openflash UEL Headers, BPB, Perrin crank pulley. Does Stage 2 BPB include UEL Headers?

Sorry for the silly questions very new to all this, Steve99 on GT86 forum directed me to your post. I read through the post an have to say 60% was German to me

Thanks for all the hard work.

Looking at that table (especially with the values expanded), it's obvious that I don't understand what's going on with this table, because the values look truly odd. Right off idle they jump up high then drop down, then do a roller coaster number (up and down, no loops) until they reach max rpm.

X Axis = % of requested torque (1 = 100% in Romraider, 0.5 = 50% etc)
Y Axis = RPM
Output = Throttle plate angle

In ECUtek the max values are 86 rather than 102 and seems to tie in better with the actual output angles, so in mine the values are all multiplied by (86/102)

That much I could figure out. What's puzzling is that you would expect the throttle angles to go more or less smoothly up as the RPMs increase, but they don't. In fact they make some rather abrupt reversals in value.

It's all to do with relationship of RPM vs actual torque output. You really need to combine that with the pedal to torque table to get a fuller picture
