Using KalMaker Workshop

[antus]

Im a MAF noob, in fact ive never used it, but from what I have gathered reading this thread there are different size and different signalling speed mafs. I gather 8khz is normal, and your bin has up to 10khz, in which case I guess a standard MAF would top out at 8khz and not use any data from above that. Can anyone confirm this? If so, did you try the 8 or 10khz scaler tables? Have you tried the other one? If you went 10khz because of the bin, but have an 8khz maf, that may be part of the problem. If you do have an 8khz maf, i'd probably just copy the data from the 8khz row to any rows above 8khz as the data wouldnt be used anyway with that hardware configuration. Like the others say though, map is plenty capable, more well known and probably a better place to start. It'll still be quite accurate and able to run your engine well.

the MAF can supply more Hz just stock tunes max out at 8khz hence why people go a bigger maf you get less frequency due to the bigger airflow path so by the time you hit 8khz its flowing way more air.now theres the modded bins that measure frequency up to 10khz which saves on needing a bigger maf so early and also when teamed up with a larger MAF can supply some huge airflow potential before the ecu is maxed out again.

All Good Opinions guys, I will keep persisting with the maf, as the supplier I got it off wants to send me work for others that buy it(but I noticed he's not selling it anymore)!
I will try the 8khz tables, as I noticed when I opened up delcewizz's xdf in tuner pro it only had 8khx scales,
but as the kalmaker had the option of the 10 I just went with that!
I'll try the other one & see how I go & if no good I will got bck to factory bin that im ran on & measure it & adjust scales by that!

Cheers all your great helps!!!!

I just checked the list of variables & there is another 6 for air metre which now may need to be changed because of the other variables
I'll list them!
the negative air delta mar
The negative delta mar tps factor
The negative delta mar coolant factor
the positive delta mar
the positive delta mar tps factor
& the positive delta mar coolant factor
The others that I think are ok are
the default load mac
the default fuel calculation mac
& the minimum hi range air metre frequency

Don't know if I need to change any of these along with all the frequencies I changed as I looked at the 8khz tables & they were even further out then th 10khz so they won't work as the car actually runs off the factory set frequencie's, so maybe I just have to manually set them, can I do this with testing readings with multi metre or may it just be one of the factors above needing to be changed?

YEAY!!!!!!
I've made a few tweaks & did as delcowizz told me to in pm put factory maf sensor back in & go to start fresh tune & make sure that works fine first & guess what!!!

IT DOES!!!!

BUT!!!
Iv'e got my inj rate right so it is at 100% stft around 1600 rpm to 2800 rpm which for any point of reference is at 270msec/gm
& then got my inj mul right so it was at 14.7 afr & it has crisp, smooth rev, but when I switch it off & then go to restart it, it won't! I have to lower my inj rat back don to around 210msec/gm to get it to start, but i'm guessing there has to be another way around this!!!
I'm guessing I just need to make it leaner while cranking somehow?
Any ideas?

[Holden202T]

personally i wouldn't be changing inj rate to suit stft at certain revs, i'd be doing the right calcs to get the right number in there then adjust the fueling to get stft etc right everywhere....

[Doctor Bob]

shouldnt the STFT be 0% ?
this would explain why it wont start

[VX L67 Getrag]

Yeah after doing a bit of reading last night, the inj rat should be set at 213.87 for the injector in the car, but the distributor of kalmaker said the inj rat was the frist thing you change to get the stft to 100% between those rev ranges, but obviously it's not the right way to go about it!
To adjust the fueling at the rev ranges do you just do that in the vefrum fuel map?
& then adjust the vefruz for closed throttle fuel adjustments?

[antus]

if its only trouble with starting, look at the cold start enritchment stuff.. you set a duration (20, 30 seconds?) and there is a 2d percentage table.. so you can richen or lean it by x %, then gradually adjust to refgular over those seconds. If your sure there is nothing else wrong, have a look at doing this.

In kalmaker STFT and LTFT are 0->200% where 100% is normal fueling.

[VX L67 Getrag]

Yeha it's not just cold start enrichment!
I can switch the car off after being running for 20mins & it was all at perfect tune% & then it wont re start until I real time with key on turn the inj rat back down!
But as I just said this should be set to the injector rates that I have in the car shouldn't it, which is 213.87(white L67 factory injectors)
So Maybe I have just been led up the garden path, do I just do all my fueling adjustments in the VEFRUZ & VEFRUM tables?
