I wish I had the XDF for this one as at the moment I was told it had VATS removed but when I loaded the .BIN in EFI Live v7.5 it said VATS was still on Class-2, plus its for a manual and I need an Auto 4L60E.

I don't suppose anyone is able to modify it and send back a copy with the changes once I upload?

I don't know why you would choose to run an EFILive COS, as you can't adjust any parameters using Tunerpro without a matching XDF.

Post the bin if you want. I can swap in the auto trans segments and disable VATS.

Hey LRT.

Here it is.
If you're able to remove VATS, segment swap the 4L60E transmission in and maybe even set the diff ratio to 2.73 and maybe set the bank assignments to SBC order instead of LS1 that would be the best birthday present ever! :)
But even just the first 2 would be awesome and get me in the zone for starting the car up.

Thanks.

Attached is the BIN that you posted, which has been converted to a 4L60E (from a 6 speed manual), VATS has been disabled, and the Cylinder Bank Assignments altered as per EFI Connections instructions for use with a SBC.

There is a bit more to it than that. You would need your gear ratio and tire diameter to calculate VSS and TOSS pulses. Then you would need to adjust a couple of dozen transmission tables (shift and TCC).

Legendary!

Thanks mate. I'll try it out now.
Gear ratio is 2.73 with 225/60/15" wheels, but I'll get an exact measurement. I can give you the .BIN file of the car the transmission was out of if you can just swap those in which would be fine.
If I don't get this OS working I'll go back to the other OS, and mayeb I can throw you a few bucks through paypal just to set up the basics so I can get it to a shop to dyno tune it? :)

Just plugged it in to the car and nothing. Quickly just checked and I thinks its just a fuse, gotta head out for birthday lunch with the missus and then will figure out whats going on and let you know, fingers crossed tho. Thanks again :)

Hi LRT,
It is so close to starting, but just not quite there.

I'm gonna try adjusting the dizzy slightly to see if I can correct it, but is it possible for you to copy the L31 spark tables from this .BIN into my one?
Someone mentioned the SBC needs a bit more timing than the LS1.

**evilstuie** · 07-16-2016

It runs it runs it runs!!!!!!!

Checked yesterday and the timing is pretty rough, and it looks to be sitting around 5degrees at start and then slowly climbs to around 20 as a apply throttle and the motor warms up. Does this need to be adjusted in the tune or by moving the distributor?

I had this response from one of the guys on thirdgen forums:

Timing table you are looking at 34-36 deg at wot, 36-38 cruise areas, and 25-26 ish idle. In 411, the table is based on grams airflow per cycle or so. A na motor typically sees .80 or so gram/cycle. I would have to double check my logs but the max value of 1.2 i hit at 3-4 psi boost by 3600-3800 rpm so i think na motors see .80-.90 and not much more. I'll confirm that later

In general stock ls1 timingtable could be used but add 3-4 deg to it in the higher rpm higher flow areas as a ls1 sees best power around 26-28 deg while a sbc typically is 34-36. Ls1 cruisetimingcould be used. Idle areas may need increased due to larger cam

Are you able to either drop the other spark tables in or adjust these on my tune LRT? :) :) :)

You originally asked for help to get the car running, so you could then take it somewhere to have it dyno tuned.

You chose to use an EFILive COS - for which there is no XDF available. Had you used 2001 operating system 12202088, then you could have used the only OBD2 XDF created, and used Tunerpro to adjust things in the tune.

It is not really a DIY (do-it-yourself) project, when you ask someone else to do the tuning for you.

Altering the spark tables, by working in the raw binary code, would be quite a bit of work. I don't think you realize the amount of time it would take to do what you are asking.

Hey mate, sorry I assumed you were using some other software so you could just copy and paste the tables into excel, make the changes by formula and paste back into the tune file. I didn't know you were editing the tune in hex.
I didn't choose the COS3, it was the OS that was on the 3rd PCM I'd bought to try and get the car running. I had the 1074 OS which had XDFs, but Dimented's LS1 Flash tool bricked them both when trying to change to a different OS, so I was stuck with what I got.
