I don't think anyone here is debating Vince's programming abilities, nor the advances he's made, in fact i may be wrong, but Terminator has applauded some of the things Vince has done. He just feels that the A/F ratio could be improved.

I challenge Vince to try these "leaner" ratios and see if there is a difference. What is there to lose?

 

i could be wrong but i'm pretty sure he posted that in his thread

he has tried leaner air fuel ratios before and it'd didn't gain anything..

we spoke of this last thing actually and what part of the "issue" might be is that vince doesn't turn the COT protection off so after some wot runs at high boost it kicks on and will make the car run richer, we're going to do some tests on an ss/tc we're doing. that had the issue pop up. it would dump to high 10's or so when COT kicks in and it happens in second gear the most because theres less stress on the engine. he said this is one of the more extreme cases of it he's seen.

so we'll be working on that and some more tweaks

he was wondering how many tuners disable the COT protection even with the stock downpipe (which is what this guy has)

 

No gains from leaning it out from 12.2 or so. That contradicts all the other tuners findings on this site. Not just on the dyno but acceleration on the street where it matters.

 

I'm not a tuner by any means, my lack of knowledge here is appalling, but even i know it takes more than just changing the A/F ratio to make an increase in power.

 

my statement stands. just got the reply to my pm. on a sidenote i guess back then his logging capabilities were not as good as they are now.

 

i think everyone will admit that .. vince himself will say he's come a long was as far as datalogging

 

hahaha....how the f*** would i forget to put the new tune on there...you must be a tard to do that....but yes my engine did blow due to detonation...this was back when he first released the software and he did not do datalogging...since then he has come a long way....yes my car has issues now...but its not due to his tune...the second time around he nailed it with the datalogging capabilities...with higher pressures there is more wear and tear and i need new valve guides...and that is not vince's problem...

so would i retune with vince again yes i would

but would i like somebody like SCT to release their 2.2 software...of course...i would love to tune my own car. and ive been playing the waiting game...and SCT has told me they will be releasing their software sometime this year...i met the CEO at SEMA and we have been keeping in touch and looks like they will have an update for me in the next couple of weeks of when the 2.2 community will have PC software to tune their own cars...

 

also.. T2 do you realize how long it took for lsj guys to realize running a 11.8 - 12 afr was ok ? like 2-3 years after they came out .. before that people were tuning for low 11's to mid 11's and when the people started saying that was a good afr they got flammed saying then why does everyone else tune for low 11's hell the gm stage tune dips into the high 10s

and the DI system of the lnf is alot more complex.. just about every tuner said low 11's was good for the lsj when it came out .. who says high 12s is right on the lnf.. just because the AFR is at 13's on the stock tune doesn't mean they dont do other things in the tune to compensate.. REMEMBER the stock tune is targeting a certain airflow moreover then a certain AFR.. bif difference

 

see i have no beef with vince, never seen one of his tunes or anything, for all i know hes the best out there..................but this i have a problem with:
he can't say theres never been a problem. he might not be aware? but there have been instances

 

jimbo

alot of the "problem" those customers have had some issues prior or have said it's been manufacturers defect that being said a tune pushin 7 psi more then stock isn't going to help the situation

my mistake I thought you had the wrong tune loaded .. I thought yo uhad a tune loaded for lower boost but again .. like you said he's come a long way

 

you know i don't know the situation with every instance and granted you can't tune around a mechanical issue. and everything we do to add more power ie increasing cylinder pressures further adds to the risk that we might face engine failure, but why cover it up and sugar coat ****...........**** it we mod and tune cars sometimes they blow up fact of tuning, but to say there never has been any problems is blatantly BS.

 

As soon as I logged a few pulls with HPT one of the first questions I asked Term was WTF is with the .74 lambda commanded and I was quickly educated in the cat overtemp protection table. Disabled it pronto and went catless shortly after. The ECU estimates the exhaust gas temp but I've seen it run over 1900*f in my logs.

 

with no cats thats cool.. disabling it stock so the ecm actually do's what you tell it to will melt the stock dense dual cats / cause problems with a high flow cat it's cool

1900 is bad for a dense cat, high flow .. it's not great but it'll be a bit better


well then we can all agree that while there might've been issues there doesn't seem to be issues with only a direct relation to tuning at least that they've been notified of of people have admitted to

 

software engineers should stay as such.
engine builders should stay as such
engine tuners should stay as such

see a trend here?

i stopped tuning ecm's for people because of this reason here. you want perfection? it won't happen over the internet.

 

What I said was: none of MY customers have ever called me to tell me about any engine failures, broken pistons or otherwise relating to their TriFecta tune.

I didn't lie, I didn't try to "blatantly BS" anyone.

However, I'm glad to see the engine failure did NOT result from the TriFecta tune. This is mostly likely why I wasn't called or notified.

 

You're treating that cat temp readout like it is real, which it isn't. It's just a calculation the VCM does internally to make that value up.

 

I said in my post it was estimated. My point being if it is anywhere close to that, it'll hurt the cats.

Still have the recall coupon for the T/A in case I ever melt those. Good for the life of the car. I guess they had issues too. (Keeping it stock for shows in a couple years, maybe when it turns 10)

 

^I was referring to Elecblue, I know you know its not a real calculation. Thats why you are still driving the car at 1900* on the cat temp LOL. A real 1900* would melt the pistons!

 

I know you know I know...

 

LOL. I know you know I know you know I know......

 

See now we're having fun LOL!
