After playing around with some matplotlib code I finally started looking at my data in visual form. I know it has too much data plotted at the same time and I have not put the RPM correctly and I am also plotting it against itself which is counterintuitive, but this will get fixed in the future.


Around the 6000 rpm mark where the hp peak is, I start feeling nothing as the RPM increases, it's as if the engine is just roaring but nothing and the rate of change of the RPM starst slowing down significantly.

It is also maddening, that whilst doing this WOT, the AW55 gearbox is deciding not to lock the torque converter. Not sure what the decisions for this were. It gets hot, and I lose 15-20% efficiency. The only reason I can think of is to prevent excessive slipping of the TC while trying to lock it during WOT.


(my intake vvt map)

Generally I find that when overtaking with the automatic transmission with an unlocked converter at second gear I quickly run out of useable torque especialy with that unlocked TC. I've had situations where I was almost overtaken by a 100-120hp peugeot or citroen even as I had stomped the gas pedal and was in 2nd. I am wondering if I slightly increase the advance at high rpm, would that help me more?
I generally am willing to sacrifice top vehicle speed for better acceleration in the high rpm range. I've not needed to exceed 140kmh/80mph except in one instance in the past year. Every single aspect of my driving in the past year has been low to mid RPM, with the occasional high rpm for overtaking or simply testing how the car performs. Torque is apparently king much more than horsepower at particular speeds.
I recently had a small race with a Honda 2.2 140hp. It had 330nm and it absolutely blew me away.

Addendum:

 I discovered that the fuel maps modified by BSR do not affect WOT fueling, and it's still lean @ 14,7 up to 5200 rpm. I have since discovered a map which when I modified, I finally got a richer AFR where I wanted.

Additionally, I have discovered that the logging rate decreases with each param I request in Dynamic Records. I am now at 80ms per data frame as such, it's roughly 12hz. I have dug seriously in the timing code and believe I have found a piece of code partially responsible for the Busy bus error but not completely.

TYPO IN MY FILE NAME
the "WinOLS (Volvo S60 R auto (Original) - 359462) 50GPHJ.xdf " is actually an 50QKHJ
-------------------------------------------------------------------------------------------


ik some are the same SW version but they have different use cases.
i should have merged them so theres not like 4214235 different gphj but i did it quick.

to check can always side by side with ols but should be good

I have read through this thread and learned a lot, Thanks everyone.
Only thing that I cannot find in my own file is the consumption constant KVB.
I have attached my original file if someone is willing to help out

Trying to find KFPNDSOL in my 40GPHJ software. Haven't had any luck, gotta put in more time. I'll attach it for people to collect and perhaps point it out faster than myself. I've beginning to think of cross flashing, it would save me a lot of time given how many map packs are out there. I don't know much of it though, would 50GPHJ software from an R flash to a LPT? Assuming they're both manual and yada yada. Getting a secondary ECU could prove useful for this I suppose.

Are you sure your car has DECOS at all? In 40GPHJ there are no DECOS maps.

Oh, this has been an oversight. lol. I forgot that was a thing, too much of a tunnel vision on the R software when studying ME. Then my fuel pressure should be a fixed value then, I see.

Alright I have a question for the ME guys. In the newer Volvo engines, how is it that they have a 10.3:1 compression ratio AND still allow for so much boost? Is it because of direct injection?

This may help you promatey. This is a running speed density. will require you to repin the maf to map sensor though

You can see in this picture the extension harness I had built to easily go back and forth from map sensor to maf
Big thanks! I missed this message early.

Yes. Direct injection engines can have bigger compression ratio.

yea 40 series and lower and not decos, they're fixed 50series is decos  we have LPT DECOS 04.5+ and all T5 and R, in the EU its only the T5 and R hence the post 04.5+ 40 series bins.

use a top hat from a pump that doesnt have the regulator and use a referenced fuel pressure regulator on the Rail so it'll scale 1:1 with boost if you're going for a higher power non decos car

you never seen this! hahha i been going through this bin on my spare time since. i have the map sensors ready, and a spare manifold to put a bung in.
one day i'll fuck with it

Thank you!

Sorry for the late follow-up, I´ve not had much spare time lately but I tried this one out in the car and it did not work well.
So I decided to go to the dealer and get the ECU updated.
Software went from 30653124B 40LKMA.A2L to 30729127A 40LPHJ.A2L, Most annoying part is that I cannot see KVB in this version either  Grin
I have attached binary read from the ECU after the update

If anybody wants to look into this file here is it https://cloud.mail.ru/public/sgtq/Gwi3tYSog
MAP grad is at 0x17CB0
MAP offs is at 0x17CB2
multipliers as for DSLGRAD and DSLOFS.
