hey guys just wondering if you could tell me the type of tune and if such a tune exist's ??

i have a vp calais, manual v6 and i want to put a L67 in it, im told that i need to get a "kalmaker" 2 bar map tune put into it, but i also want to run an "Air 2 Air " intercooler wich im told will require a new tune now am i looking at a huge amount of money or is there a tune like this already ?? also i want high ratio rockers so not sure if that would come into it or not, any help would be much apreiceiated.

cheer's,
Ethan.

ok firstly, there is no tune you will find anywhere that is going to do what you need, its going to need to be made as you go to suit your mods.

secondly, are you saying you need to put a 2 bar map tune into the vp computer or into the super 6 computer ..... there is a big difference here!

you have two options as i see it ....

1. stick with the super 6 computer and tune it to suite - there is plenty of info on here to help you do what you need and it doesn't require the dollars an aftermarket computer would cost

2. convert the engine to run on a vp computer and then add the 2 bar map etc and go from there .... this option would be preferable to me as i am more familiar with tuning the older computers ..... having said that you would loose functionality like sequential injection and such ..... but then it has the flexibility of better code in $12P.

Just to be clear kalmaker is commercial dos based code that allows you to support boost (among other things), and 12p is our code, which supports tunerpro 5 in windows (http://www.tunerpro.net) and can be had for free from this site.

you would be surprised what the standard tune can handle on an L67. if you put the super6 wiring loom and computer and airflow meter etc into the VP, then you can pretty much run as is on the stock tune. in my experience, you only need a tune if you run a pulley > 10psi, tho I havent played with the tune using an intercooler yet. the L67 I work on is in a Mazda ute and it just being assembled with a W2A cooler and a cam at the moment. will be tuning it soon.

well "holden202" i was told get my vp computer tuned as the L67 never came manual and my car is manual so with the L67 engine it matters with the computer im told, so how do i get a l67 manual computer if they never existed ?? so i was told to use the vp computer and get a 2 bar map tune put into it. is there a way that you can do something to the stock l67 computer to allow it to run manual ?? or can i use a manual vs computer and get the boost setting put in if thats possible ? im really not sure with computers but i know a bit lol. any more advice would be awesome!

cheers, Ethan.

my mates running a stock VX L67 computer and wiring harness in his mazda ute with a T5 manual. just leave the plug to the auto trans hanging there disconnected. I just took the tune on it and ticked the manual flag (yes its that easy) and it was away!

in all ecotec engines, the Manual and auto computers and looms are exactly the same (bar the missing wires to the auto trans) only difference is the disabled auto stuff in the tune.

your best bet is to run the L67 off your VP computer with OSE code in 2bar. You will need a custom tune with A2A which ever way you go

sorry but I have to disagree here..... just use the stock L67 harness and tick VATS and Manual trans in the tune, reburn and drive. will avoid having to do a huge complicated remap for map based tune if you go 2 bar on the VP computer.

wow i thought it was soo much harder than that lol. honestly if its that easy to just change the computer over to manual i wouldnt even bother with the a2a it seems like alot of hassel. would i need to change the computer at all to run a higher boost pressure ?

up to 10psi pulley you can run stock untuned. (we did). at 14psi pulley, we put a 74mm MAF on it, remapped the MAF tables for it, and removed 5 or so deg of timing to stop it hitting knock retard.
now its got a w2a cooler will be remapping it again, but to be honest, my personal opinion is that the stock tune will handle an A2A cooler.
