auto ve for ls2

[oztracktuning]

How can i unplug the Maf and still get IATs in an Australian LS2 so that i can get the VE table accurate in speed density mode ??

I want to do this and then dial in the maf perfectly. But the IAT and MAF are in the same plug. Is there a simple solution ? or am i overlooking something?

I used a spreadsheet to develop what the injector flow ratings vs map should be and put that into another spreadsheet. Then, I took the maximum value and figured out the percentage difference at each map level. Using those values, you can scale the area of the MAP to get yourself at least in the ballpark to do an auto tune. It just complicates matters a bit, but it is a decent work around.

mind posting a copy of that spreadsheet? i've been working on something similar lately, but i dont wanna reinvent the wheel...

I thought I read something on the ls1gto site about guys taking the MAF pins out of the connector and plugging it back in with just the IAT wires.

Another guy made up a little converter with the correct plugs to take the 5 pin in and only connect the IAT 2 wires through the other side into the MAF.

Maybe start with option 1 until you have built an option 2 adapter ?

The problem is i need it to go mafless just temporarily while tuning the car.

Thats ok either method is reversible with a few minutes.

Just buy a male and female MAF plug socket and join them with the 2 relevant IAT wires. Use it in the middle of the pcm maf lead and the actual maff connection when tuning and remove it when finished.
Job done.

Can both the male and female MAF plug socket be bought easily

Someone here posted a link to some dude who sells all the stuff. They were dead cheap. It was a member on here.. Maybe someone will post it back up.
