[s-cars] FW: POS testing procedure

[JC]

Meant to CC this to the list...

> Wylie - the fact that you're losing another cylinder makes me

> junkyard and try swapping on either side to see if your
> problem goes away. POS swapping is the one thing that IS
> super easy for troubleshooting vs figuring out coil problems..

> if you were local I'd toss you one of my spares for

> internationally I'd just mail you down a spare
> tomorrow(you're Carolinas, right? if I don't have you mixed
> up with somebody else?) but I won't be home for another 3
> weeks or so. then again you're in the south - you must have

> it'll act up just when you can't do anything about it..

> the other "cheap" option is as mentioned the LS2 kit, say

> it still dropped out at the very highest levels of
> throttle/boost (I'm on a very late generation TAP chip,
> pushes 1.6bar+ on the gauge - nothing outrageous but nice and
> solid).  after us putting in a lot of time to try options and
> troubleshoot, he nicely refunded me and had to admit some
> ECU's just don't seem to be compatible with the LS2 coils.
> I'm betting it's a max current thing, maybe my ECU has weak
> output transistors or something, but anyway a lot of people
> have had excellent luck with his kit and when it ran on my
> car it ran great - seemed like a bit more power even right up
> to 7/8 throttle... but then past that I'd get cut-outs, and
> who wants an S-car you cant drive at WOT!?!?  like the 1.8T
> the other benefit is the LS2 coils are available at any
> autoparts joint on the side of the road vs. the stock Beru
> units which tough to find outside the dealer and you have to
> pay for in solid gold bars.

> That said, AutohausAZ has them at $130 ea. which I'd noticed
> some time ago but had slipped my mind.
