The purpose of this thread is to help fellow FP Red owners looking for input on their timing maps/ fuel maps using EcuFlash. I do not recommend dropping these values into your ignition table, NOR the fuel values, FOR REFERENCE ONLY!!! I will not post my MIVEC map as I was given this by Aaron @ English. It's unique enough for me not to post it

Here is a datalogged pull from my Racegas tune. 3rd and 4th gear


I need to figure out how to eliminate the shift knock... it's quite annoying.
I also need to run MORE boost. I've maxed out my WGDC at redline... How do I get more boost to 8k? Let me know what you guys think!

your shift knock is overated. 2-1 is nothing so you don't need to worry too much about it. Nice wot data.

In other logs I've gotten shift knock as high as 8. It pulls timing and makes the car sluggish entering the next gear.

You need to smooth out the timing between shifts, look at the loads cells and timing values, there is a huge jump in timing. You need to lower the high RPM, low load cells timing values.

Joe,
What kind of timing advance would you suggest? 20 degrees?

gsrboi80

iTrader: (38)

Nah man you shouldnt have to back it off that much try lowering a couple degrees at a time

Ok... I change the maps tomorrow and hopefully get a nice 2nd- 3rd gear pull to look at afterward.

Why is your high load timing so low (with race gas) ? Your timing maps don't look very smooth (some large jumps), but maybe you never are in certain regions of your map ???

Also, I would have thought your load would have been higher than you are mapped for (320).

I would re-scale the Timing/Fuel Maps and add 290/300 load.

Also what's up with your airflow? 1500hertz only?

Your race gas timing numbers are quite similar to your pump numbers. You are leaving a lot of power on the table with the race gas I think.

I would start there, if you are still getting knock go lower, if not you can try raising it.

I remember having shift knock, 1-2 sometimes 3. never above this though.
but my fix was playing with MIVEC and more timing smoothing. But I think MIVEC decrease had more results.

He isnt logging 2 byte airflow. Shift knock can be cured with a timing map that is something like this:

So let me get a couple of things straight (we are so far OT anyway)

You are actually flashing two seperate maps when you switch to race gas instead of just flipping your switch for the tephra mods? (Since your boost adder is different for the two tunes and you are on the same tables). You can just leave it at 22.7 and set your pump map to [boost] - 8 psi (your adder) similar to your race map (IE 14 psi in the upper RPM cells.

You aren't using NLTS on what looks like a drag map?

Your boost doesn't really fluctuate at all at different RPM ranges?

You require near 100% WGDC on a red for 32psi? ...even with the actuator at 23psi? I was under the impression the Red held much better than this. (but I don't have any experience with one yet). I would also flip all of those 0% wgdc cells to 100% and then drop down to 85% the cell before it spools (your 3500RPM cell if your map is correct, however the 40% might be in there to keep spike down).

I'm also curious why you are only hitting ~300 load. I would think that you would be much higher in the 340+ area with a Red. As a guestimate I don't think your timing is too far off, but thats just a guess (again, no experience with the red). With that level of boost I can see 15-16* near redline being plenty, but the numbers are a little jumpy.

I'm curious to see the MIVEC map. I think it being unique is all the more reason to post it, but thats just me . The only thing preventing me from posting a map is if it is a standard vendor flash.

----------

On a side note, thanks for the example JB. I hadn't seen any concrete examples about what to do for shift knock yet.

sorry to take it OT...

+1 thanks for posting an example. thats a huge jump from 70 - 80 load tho... Im assuming during shifts, your seeing it come all the way back to 80 load? I never payed attention to the load in between shifts... until now. I just started lowering/smoothing the cells from 100 up to ~ 180 load, each rpm point from 5500, on... Im gonna check to see how far back my "load" goes back during shifts... Good info!
