Setting up for first log for calc vet tune.

[joecar]

Wow, that came out pretty good, MAF was already good, VE table also pretty close...

[joecar]

Before you do a WOT pull, check your B3618 PE table, it is too lean, EQR 0.862... you will want to change this to EQR 1.16 or EQR 1.165;

check which fueling units you're using in the tunetool (Edit->Properties->Commanded Fuel Values) set it to EQR, and then restart the tunetool, then edit B3618 as above.

Also, you might want to copy B3616 to B3615 (B3615 is too restrictive down low).

After your B3618 is set to a safe value, do a WOT pull and see what the maps show.

Hi joecar,
I just wanted to clarify what you mean by WOT pull. Is that pushing your foot to the floor and waiting for the engine to catch up?

At the moment when I do this the engine flutters as if it does not have the fuel or air flow to pull through. If I progressively feed the throttle I have heaps of power. I was hoping this would be eliminated once my tune was adjusted to suit my setup.

Would this be because of the low EQR on B3618? Now that I have raised the value of this should my WOT Pulls be a lot more responsive?

Cheers,
Laychut

You need to look at the log (map) like Joe says and find out what it shows when it "flutters"... Yes, WOT means on the floor - but if it is not running smoothly when you do that, dont stay in it long - just long enough to see some data to determine which way it is going... Post up the log.

[joecar]

Edit B3618 to make the PE EQR safely rich, and then do what BLK02WS6 said.


( the cause may be B3618 being lean at EQR 0.86... but it's best to not assume anything, it's best to take a log and analyze it )

Hi Joecar,

Should I keep using the Calc Vet PIDs or should I log some other PIDs when logging the flutter?

[joecar]

You might need SPARKADV, IBPW1, IBPW2... you can remove MAFFREQ, DYNAIRTMP_DMA, CYLAIR_DMA.

Hi,
I have completed a WOT log and also a log that captures the flutter with the extra PIDs we wanted to monitor.

WOT Log - Calc Vet Wot Pulls.efi

I used the Calc Vet PIDs for this log. I had increased the EQR on B3618 to 1.16 as suggested.
While carrying out the WOT logging, the fluttering was a lot better. I only noticed it once. The engine seems a lot more responsive.


Flutter Log - Flutter.efi

I deliberately made it flutter. I am starting to think that maybe the shift points for the kick down is set too high or something. I can alway get it too happen when I am in 4th gear and sitting on 100kms. If I plant my foot it will flutter until it gets to 110kms and then it will downshit to 3rd. Once it is in 3rd it powers away.

I have also noticed the same beween 2nd and 3rd on occasions.

Current tune - Cal Vet Tuning_0003.ctz

I thought I would post the current tune I have loaded.

Cheers,

Laychut

I'll analyze your logs thru-out the day...
