Vlad's rides thread

is it me but did you just pull ~9 sec 0-100 in that thing?

less, I count high 7s going by the timeline, 9 is stock out of the factory.

By the sounds of the fuelling there's still more in it.

its only in the cruise areas its suffering. flat out it smells fine, (spent gunpowder smell= good AFRs underload)

Will try to install the WB tonight. The reason it has been such an improvement is the ignore knock count table in this tune has been maxed out, the engine is rattly as so the original $FB tune was pulling heaps of timing in my theory, Its a greenfoam tune and had the same spark timing as this one except I had the luxury of tweaking (reducing some spots) it on a dyno from this very original table I copied from in the first place. So its gone full circle.

thats way impressive.
way excited to get into my VN just re-sealing the V6 and re-doing my injectors at the moment. best i start a thread. love your work dude.

[vlad01]

You can use my tune if you like after I dial in the VE table. Should be virtually spot on for your car, maybe a tweak here and there for the differences.

[psyolent]

love to give it a go mate. see if we need to disable the knock depending on how rattly the old v6 is

[vlad01]

even in my mint VR with very quiet low K engine picked up random false knock like crazy, I would say one that actually rattles would be pegging the knock retard all the time.

Anyway, made a patch cable with OBD style connector so I can use the ALDL adapter, wired up the WB after much stuffing around trying to figure out why is didn't work. Turns out years earlier I wired the heater wires randomly as they were the same color, but there is a proper order which I have my WB using a 4 wire O2 plug to get its power, ground and feed the NB simulated signal, WB being a separate 1 way connector. So my power was ass about and also being a NB originally the NB ground is an isolated one so i had no power ground for the WB, I ran an extra ground to the manifold and now it all works.

Did some quick tuning in the shed, found the cruise and areas near idle to be very rich, dropped those areas by 10-15% and now its close enough to use VE learn, the higher Kpa areas seem to be pretty good. The NB came out black so I most certainly had it too rich. It was pegged off the rich scale when starting up so no wonder the engine misfired in that period, it was about 2-3 AFR richer than commanded. Got my laptop in the car if i fancy a log on the way to work.

So been driving around at work with the laptop on whist VE learn on and using that to tune hands free. Going real well and gained a lot of economy and even more low end torque. Still top end is actually quite rich, abound 11.8 across the broad. So will log those areas at some stage and change it manually. Need to look at dealing with the bunny hopping, since now the AFRs are good there the torque has rocketed up to the point its a bit jerky as it was before with the greenfoam tune, the lash in the drivetrain in this car is whats making it a problem, unlike the tight VR drivetrain.

Might look into this idle drive, and try to disable tip in/out bump and run only idle drive.

On my car backing off timing in the area that's bunny hopping made a difference.
Richer or leaner AFR's didn't do much in my case.

[vlad01]

it was so rich Im my case it did actually make for nice idle drive and smooth take off due to lower torque, now its just angry.

problem is dropping off the spark in those areas is where I cruise a lot in in the higher gears so there will be lose of torque reducing economy.

The lash is multiplied inversely to the gear, so the main factor is drivetrain lash, there is a fair bit, as you would expect a T5 abused all its life just shy of 600,000k
