[Tuning feedback for the software]

Hi all,

I've found VTS pretty good software so far and I've come from a PowerFC/Datalogit background so my feedback might be skewed (apologies for this)

Some tuning feedback, at least from my experiences

- there should be a way to plot min/avg/max on the IGN or fuel maps to help you manage and track the inputs - ie avg water temp correlated to the fuel map or IGN map

-- you can then use this to fine tune load points and correct based on other inputs (datalogit does this pretty well)

- there should be a way to view # of times each load is used in a log file to help you understand how meaningful the log file is and # of samples per load cell, useful if you want to adjust cells but only have 2 samples - ie dont consider avg water temp if you only have 2 samples for that load cell, need more samples to be meaningful (datalogit does this)

- ghost trace or "snake" trace doesnt work, at least when i am trying it, i cant see no snake trail or "ghost trace"

basically i want to work out what cells are used by my log file, it looks like the VTS software supports it, but whenever i turn it on / try and use it - i see no trails/no snake - only active cell tracking (am I doing something wrong?)

what is the representation of "section time" is this milliseconds or seconds or some arbitrary number in the logs?

is it possible for the logs to reflect cell X and Y number that it's using from the tune in real time

ie

SPEED,RPM,MAP,ECT,LOAD_CELL_X,LOAD_CELL_Y

67km/h,4400rpm,156kpa,78deg,5,7

which would reflect using RPM cell 5 and load cell 7 from the 2d or 3d map (helps track what cell the ECU was using at that point in time)

re: DI3/ speed

ok did some on road testing and watching DI3 value, it's spot on, so ive got no idea why its whacko in the logs?

one thing I did do however was the gear judge was set to 5spd and my car is 6spd, so ive set it to 6spd and started doing the gear calculaitons on road.

does gear judge play a part in how the data is shown in the logs for speed kph???

here's what my logs currently show before I changed anything

Engine Speed 2013

MAP 49

Speed -DI3 kph 3.7

DI 3 Frequency 27.2

ie my speed is 3.7kp/h - which makes no sense, at 2013rpm. its more like 27km/h - is my DI3 freq actually just KP/H ???

ok thanks, thats fine for knock control, ie backout timing, add fuel based on knock events

but what about basic knock logging from the factory knock sensor?

cant this be wired into one of the analogue inputs to display values in the logs?

hi all,

is there a reason the vipec cant use the factory knock sensor?

i would like this input data for my logs to tune the low load IGN areas, but cant do this without knock input.

i am used the apexi powerfc where knock input is standard via the std knock sensors.

sorry, no problems, will do on the weekend

hi,

i did some checking tonight and here's how ive found the DI's are mapped on (by pressing buttons in car etc)

DI 1 - no idea

DI 2 - AUTO intercooler spray button

DI 3 - no idea

DI 4 - AIRCON button

DI 5 - START KEY

DI 6 - IGNITION ON

no idea what DI1 and D3 do - is it safe to change these as per your recommendations?

ie upload your PCL file and update firmware?

thanks for your detailed help so far. I haven't actually changed anything yet but I have noticed in my logs that speed does show up, but the values are completely whack ie 3km/h

see attached image

is it just the calibration is way off or something wired?

[EVO 8 V44 plugin - no knock or speed input?]

thanks, ill give it a try

it is an evo 8 and the ecu is definetly installed in an evo 8 - with an evo 8 engine

perhaps this ecu was pulled from a working evo 9 and the guy (or girl) who installed it simply used the old evo 9 settings

thanks

what is the significance of the digital inputs being wrong?

the car runs pretty well and drives, aircon works etc so id be pretty cautious fiddling with the digital inputs.

whats the worst that could happen if i change those DI's to what you've stated here?

Hi All,

Got my new car, Evo 8 running V44 plugin and I've noticed in the logs there is no knock #s or speed values?

I would have thought being a plugin model this would work off the bat? or is it not enabled in my tune or something?

Attached is the tune file. Also need to work out some of my start issues, sometimes cold start is 2500rpm+++ idle and other times hot start, starts and will then stall if I dont touch the throttle
