L76 tune
My Ecu is on the way to the tuner, and i need to know what to tell him I need. This is what I can think of:
VATS off No rear O2 sensors No aircon\cruise control One fan switched off the high speed pin (temp 95 deg?) Intake\header details Wipe it over with the magic rag I assume this is the basics to get it to run, then after that he puts a decent tune in for a stock engine with MAF - any thing else you guys can think of? Cheers :) |

Just a question...why retain the MAF? |
I know opinions vary on this, but advice I have on this is that the L76 100mm maf restircts airflow very little, and the benefit of having it outways a few extra kW. I need it for engineering anyway (I know I could mock it up) so have decided to put it in and leave it for now.

after u get the car started u need to get a scanner onto to it
then get all the error codes that it throws out and write them down then find which ones are not applicable then resend the ecu to the tuner and get him to turn them off all the ecus i get these days have my custom tune which actually fixes the fan problem on some tunes |
as sideshow said you really need to stick a scanner on it once you get it back and started so you can see the rest of the codes that are on it..
there will be a few "lost coms with" errors for all the other devices that you ECU cant talk to like ABS and BCM there will be a crank relearn code if the PCM is brand new possibly a few fuel level sender errors generator light, starter relay circuit maybe those are just a few that will more than likely pop up. |
Some good tips - thanks - Look like its a matter of letting the tuner know everything Ive left off from standard wiring. :)
Technical Q -Do you guys hook up X1-9 to the brake switch - someone told me that may be used in throttle control - or is it just used by cruise control? |
cruise and aslo for diagnosing with tech 2
|
So worth putting in then? :)
|
its used for cruise and power tourqe management.
if the tuner puts a tune in the for some decent power then he will disable torque management any way (easy way to make the engine feel like a totally different beast) .. so leave it out. if you dont mind me asking who are you using to tune it? |
Oztrack. Pretty well known on the LS1 forum - Sort of stumbled onto gettig a tune from him.
As an aside -I recognise your nickname from LS1.com - so Im sure you know of oztrack - we have conversed a number of times on L76 conversions over there - i have a feeling we may have met before too...Ill send you a PM. Cheers. :) |
Yes ... know Steve he is a great tuner. He will be able to sort out all your probs.

Good choice. Steve did my tune. You are right about the less restrictive MAF in the L76. If Steve has advised you to leave it in, far from it for me to argue. |
good thing with goin mafless is u save 250 bucks on having to buy a maf meter and u dont have to wire up the missing maf plug
i have 2 sets of ecus one for maf and another set for mafless and when u run mafleess we then wire up an ls1 air temp sender in place of the maf meter cause once u remove the maf u loose the air temp sender |
