Will do. It will more than likely take a while as I want to try & make it run off a custom pid for roadrunner use instead of making educated guesses & confirming. Though ultimately this may be the only method of getting it close in a small enough timespan.

if you can find a good way to get it in line, that may spur me to get a roadrunner. hehe

What happened???? I went away for a month and R&D came to a halt? :hihi:

Anyone still playing around with the transient tuning? I'm about ready to get back into it.

Hi Howard. Since you had a holiday we all thought we better have one as well.:grin:
Seriously though my fuel pump woes are getting worse with the hot weather we are having, so testing is on hold until I can fix this issue for good.
On a brighter note I have upgraded to the V2 unit & along with the serial AFR logging once my cable arrives, (Thanks Andy) should give some good accurate data to play with.

Good to here you made it back in one piece Howard.

I have got a little side tracked with some OBD1 stuff...:)

Glad to here your truck is running well enough. Also good to see them fuel prices go down under a dollar. Now you can afford to put the good fuel in the burb.


Things have been quite in this department.

Sorry, need to through some time at them early Holden's to fill a gap.

The code in them 1 meg PCM's is busy and I will need to put more time into it to make something of it.

enjoy

3hours ago???? What the hell are you doing up at 2.30am Mick?
Get to bed!!!!

I thought the same thing, it was late.

I have an interesting day today, just getting some software in order for the early Holden's.

This should be fun.

Hey guys....I tried something I hadn't yet tried. I set all of B9000 to 1.00.
Burb would not start....blew smoke and rich as hell.

DESC.001 = Impact Factor determines the amount of transient fuel compensation to be added (the height of the parabola).
DESC.002 = This represents the fraction of the injected fuel pulse that will impact the port wall.

Howard,

So by setting it to 1.0 is it saying that all the fuel will wet the wall...?

I need more enlightenment...

:)

Yeah...I'm not sure Joe....I was just 'trial and error'ing'.
It deffinately would not run. As soon as I changed it back and cleared the flooding...it fired up as per usual.
