PM6 running LS-Vtec....having some issues
Guys,
I got my LS-vtec motor running with a tune i made for the car and she just wouldnt idle. I could get it to run for a min or so and then it would die out. I decided to burn a stock PR3 map and try and see if that would make any difference and it did...sort of. The car would now run and hold an idle (barely) but it ran.
Now i was playing the with the options in TE, and it wouldnt let me change the injector sizing for the PR3 mapping. My idea was that if i could program for 440cc injectors on the stock PR3 map, it would at least let me get a base idle and I could go from there?
any ideas, cuz im currently stumped

Re: PM6 running LS-Vtec....having some issues
You want to give more information on your seutp? ...are you NA or Turbo? 440cc injectors are what you're using, or are you trying to make it work with that? When you load the PR3 map, are you just copying and pasting, or are you lining up the columns? ..before you scale for the 440 injectors, are you scaling the overall map for the larger displacement (PR3 = 1.6l.. LS = 1.
..
We need more information.

Re: PM6 running LS-Vtec....having some issues
I guess more info would definately help hehe..
motor:
LS-Vtec
B16A2 head
B18a1 block
mahle 9:1 pistons
scat rods
honda bearings
etc etc
T3 60 trim turbo
38mm tial wastegate running a .2 bar spring for first 2000kms in breakin, moving up to a 1bar spring shortly after
3" dp
440dsm injectors
starion front mount
running on 1 wire vtec on TE OBD0 ecu in a PM6
i believe i was copying the map originally and not lining up the columns, that could one of my probs.

Yup yup.
You should be able to tune the idle "close enough" by listening to idle quality, smelling exhaust and fiddling fuel. You can see your vacuum readings on a vac/boost gauge, and your tach tells you the rpms - just highlight a nice block of fuel values, 3X4 chunk or so, and modify the whole range up or down.
This is ***uming you haven't fouled out + ruined plugs, making for an untunable situation. Or that you don't have a small vacuum leak. Or injectors crossed up so that they are firing at the wrong times for each cylinder. Or a bunch of other stuff, all small stupid and annoying problems we all make.
TRUST me, the more you ---- around with your car the more you will ---- up and - oddly - the easier it gets. "Oh, it must be somthing stupid, let's poke around a bit and see what we can find."
