Hey guys,

Sorry for creating a new thread, wanted to bump an old one but couldn't find the nice informative LeanSpool thread JCSbanks was involved with.
Anyhow, i'm getting there with my fuelmap, thought I had it down pat last week with 3 back to back pulls to try and level out the LeanSpool difference.
I really want to keep it atm as my car is incredibly nice and crisp at light throttle, although the stock 9.8 turbo prob has a bit to do with that.

Anyway, had a run tonight with a mates Silvia he just got back, and did several 2-3-4 pulls the last one being the one I had logged.

Here's the VD of my fuel tuning last week.


And here's the log from last week attached: 20/11
And the one from tonight's 2-3-4 attached: 26/11

A weeks difference and suddenly in 2nd its high 11's which is fine, 3rd mirrors my tuning efforts last week pretty closely, however 4th is over half a point richer again, deep into the 10's.
For those that dont' run LeanSpool and have in the past, is it possible to have the car feel very similar with it turned off? (start/stop rpm 2500).
I know there's delay and decay timers to help sort this out, however i'm running 90550001 V5.10 which doesn't have this defined.

Cheers
Ben

 

do you have boost log? I'm thinking it might be due to higher gears showing higher boost levels at lower rpm and maybe ECU dumping fuel? Just a thought. Anyway gear dependent boost might help out if available for your rom if above is indeed the case.

Good Luck

 

Boost log is in the attached logs and visable on the graph above mate.
It was a 2-3-4 run, so changing at ~6.5-7k drops the next gear in at ~5k which is accounted for in my 3rd gear logging and tuning of the fuel map.
On a normal 3rd gear pull I start between 2-2.5k, full boost is usually mid 3k.

Gear boost isn't available for my rom YET.

 

leanspool is something i like to disable on all cars.

 

Do you do so via Periph or setting the start/stop values the same?

 

periphery is the best way, but I do both...

 

Periphery 1 (FBA) > bit 0 = change from 1 to 0

 

Thanks guys.
