Good morning,
I have searched high and low and can find
LITTLE info about these ECU's. I know there was
a guy with a Aircraft project using one, and
someone on this list wanting to use one. I now
have 2 of them, one '90 Storm 12-Valve (4cyl,
SOHC?), and a '92 same engine. I know they do
not have a traditional EPROM (27C) instead they
use large square (QFP?) packages. I would like
help programming this or building a interface for
my programmer to hook up to.
Most companies that use this ECU (for Turbo VW
use) simply put a pot on the MAP sensor input,
and on the TPS and label it LOW and HI. Some have
4 knobs but, I'm not sure where they tie in at.
Would this be enough for tuning a NA 2.0L Type 4
VW engine? I would like to turbo it soom as
funding allows, can I just stick a 2 bar MAP on
it, or does it need programming also? Thanks for
any help you guys can provide!!
-Bobby
