Tuning questions...

[Joshuah Stedman]

ok so I just got my safc and datalogger installed and I have a pocketlogger setup for tuning purposes. I know How to tune, it's just that I don't know how many lbs of boost I have to play with before my fuel system poops out on me(stock injectors, rewired pump)?

Also how can you measure the duty cycle on palm n' stein? All I have is pulse width, can you use that in the same way?


any help would be appriciated...

What kind of turbo? and what kinda fuel pump/injectors?

(RPMxIPW)/1200=IDC

now I cant get my fu##ing logs off of my palm. Im and the palm and stein screen and it says hit transfer and i do and it just goes away....

I myself never liked palm n stein and dont know anyone that uses it. I would download MMCD. Its a lot better and I trust it. Its also a lot easier to use.

I would start off at 15psi. If you dont have a WBO2 I would be careful. The stock afr is really rich and you will most likely need to pull fuel before adding even if upping the boost. But I dont like leaning out a car without a WBO2. You can easily burn up a valve.

Scroll down and take a look at the 1g timing table. If your timing deviates from this then you know your knocking.. thought this might help you.

I have mmcd, but my 02v is weird... it's says it has like a 2.5v on the sensor at idle...

and Is It any use to tune a little with the stock injectors?

get a wideband ,without a wideband you are tuning with a blindfold on

as for the injetor it all depends what do you want to do with the car ?
what turbo do you have ? check your IDC are you knocking

money, without the money I cant get a wideband. haha

 

[JayRolla]

Dont do any tuning untill you get money then. Its a lot cheaper to buy a $200 wbo2 then it is to rebuild a head just because you wanted to gain a few HP out of the stock injectors.

Tune for knock. Use that link I gave you to determine if your curve is decreasing or flat lining (knock).

there was no link, but I looked it up and my timing curve is good i think. Im around ~20 deg. of avance @ wot @ 16.5 psi.

Oh what the hell. I dont know why it didnt paste. Well here you go, scroll down to the bottom for the 1g table.

The DSM ECU Timing Curve

Us 1g guys dont need to use the timing map to look for knock. Our dataloggers actually read the knock the sensor sees.

To the OP if you are seeing 20* max then you are getting a little knock.
