Air Flow Meter Conversions. Chips Vs. Split Second. Why Split

["Neil Deshpande" <Ndeshp@xxxxxxxxxxxx>]

Second is cheaper than a chip.

Rob:

I had put out a similar mail some time ago and was replied to by Jim =
Conforti himself.

Reprogramming the ECU is most certainly the most elegant way to go.  It
=
has been done for the E36 (M3 only, maybe) and you can see Duane
Collie's =
comments on the system's performance on Turner Motorsports' WWW page.

Reprogramming the ECU takes tons of dyno time.  There are apparently no
=
equations that can give you the engine curves, etc., and one has to =
determine them by experiment.  Of course, a custom chip can be written
for =
any engine mod (this one included), but it would not be cost effective
to =
do it for the E30 since enough E30 owners would not be interested.  I =
guess the $850 that Split Second charges is lower than what Jim C., for
=
example, would charge to develop a custom chip.

The Split Second system is expensive due to the fact that it is more =
versatile and the chip would be cheap because it would be hard-wired to
=
one applicaion, PROVIDED you sold enough of them.  If you did not sell =

enough, it is better to sell enough of an adaptable system such as the =

Split Second so you can get the numbers that way.

This mail is based on my understanding of Jim C's mail to me and the =
Digest.

If you do carry out the Split Second conversion, I would be interested
in =
the results.  I know that Russ Poffenberger in Sunnyvale, CA,  intended
to =
do this and has not had the time to complete it.  I could contact him
and =
perhaps he would be able to help out.
