Hi Joecar, I used basically the inverse of your equation in version 7.5 ( '{}' is the clue to version) and LS2's do not have GM.INJFLOW or an equivalent.

I have been trying to calculate fuel economy custom PIDs in V8 in Litres per Hour and Litres per 100 kM. Each time I performed a division using a PID all I got was a full trace of zeros. eg /...
My VZ would practically stop when the TC cut in, so I decided any change was probably better.
As a first step I simply reduced B6603 TCS Spark Retard by 50% and the result was great. No wheel spin,...
I don't suppose some clever bod has produced a set of numbers for B66** numbers (LS1) cotrollers as a jumping off point and would be prepared to share. It would be greatly appreciated.
I should have read this earlier, I always had the feeling that I needed to add the weight of my fat ass to get close to an accurate figure.
Cheers, Steve
Hi, as far as destroying cats with LC, I just dont believe it. There is a world of difference between lean under load and lean cruise. At LC the cats should just switch off and cool off, after all...
At this concentration the only probable benefit is the cleaning effect that the acetone would have on the fuel injectors. As far as the possible problems that the acetone could could cause, keep in...
Hi. My understanding is that the 150 seconds is to maks sure that lean cruise only operates on the highway. I have set mine down to 15 seconds on the basis that I want lean cruise to come in early,...
I cant find this posted anywhere.
So here it is, with plenty of time to leave hints around the house for Christmass.

I have a 5.7 VZ Commodore which has a large number of tables to adjust settings for 0 to 80 percent ethanol.
Instead of using the sensor input for it's intended use, I think that it could be used as...
I have been looking at the idea of adding hydrogen and oxygen to motors since the 1970, but have never bothered to do it. It could only help economy and I prefer power:angel_innocent:
This is what I...
I have a generic set of curves for a petrol engine. The diagram comes from a text I 'liberated' from the internet, it runs to over 1100 pages but it does have a lot of theory. The basic problem is...
Presumably you are chasing better fuel consumption. BMEP has a little to do with it, unfortunatly, you have chosen a car that really never needs to operate a large throttle openings. At low throttle...
Well, that was quick.
The wideband is a Techedge 2J1 which does have serial output, so I will crimp up a custom cable to connect to the V2 for some of that good ol blackbox logging. BBL is really...
My car (LS1 VZ Commodore, Australian) has its cats mounted very close up to the exhaust manifolds. The oxy sensors pass through heat shields that cover what little pipe there is and I want to add a...
The purpose of the dedicated accelerometer, when acc can easilily be calculated by the rate of change of vss, is that if the road is not perfectly flat then acc reported from EFILIVE does not...
Have a look at the link below for some theoretical background on E85.
http://www.ls1gto.com/forums/showthread.php?t=264727
It suggests around 9.5 to 1 for stoich for E85, so at max power the...
Marco,
Take a look at B5908, Fuel mixture spark correction. It adds extra spark when lean cruise is active, it is used in all the Holden tunes and it improves the throttle response. This can...
I read an interview with the/an tuner for HSV and the question of lean cruise came up, his answer was that they did not consider that it was a priority for their customers. He also mentioned tip in...
I have just ordered an accelerometer development board, based on the chip used in laptops and Nintendo Wii's to sense movement. It can output acceleration in 3 planes from 0 to 2 g plus or minus, as...
There are two types of SD cards SD (Generally up to 2 GB in size) and SDHC - High Capacity (Usually 4Gb and above in size).
EFILIVE only supports SD cards I believe. 2Gb is a huge ammount of...
There is a readme file inside the zip, it says.
Extract this zip in to :\Program Files\EFILive\V7.5\Calibrations
When you next load a tune file you will see a option at the bottom of the engine...
Thank you gents, clearly the post that I read was not on this forum. I really like the concept of lean cruise but will wait until I have a wideband connected before experimenting. I have just checked...
I remember reading a post (but not where I read it) that suggested that Lean Cruise did not work with a Mafless tune. Does anyone have any thoughts or data on this?
Thanks, Steve
What WOT? But seriously, I've had the anchor in the passenger seat a lot lately ( since Oztracks tune went in ) so revs and throttle have been limited somewhat.
But the few chances that I've had...
