Re: LT1 DIS or CoilNearPlug Almost here

[Len Sabatine <sabatine@epix.net>]

  Roger , Sequential LT still maintains Opti Encoder  to sync Injectors 
.  Their Xducer may or may not work correctly, Should I have Electromotive
  folks custom configure the basic electronics , we will be utilizing an 
OE pickup,  our LS1 Coils and custom coil harness. We're going to be 
testing this on the
  Dyno against the OptiSpark system, which Btw , hasn't given us any 
problems , in 2 seasons of usage. There were issues with 92-4 housings not 
being properly
 ventilated . Hence the bad wrap about OptiSpark. Just replaced one on a 
93 Z  which had 155k on it and never was previously serviced. Still ran , 
lay'd down
 under load though. Referring to your experience , some commercial 
transducers aren't  properly hardened for the harsh  Automotive 
enviornmental conditions.
 For test purposes , we aren't terribly concerned about the cost 
,  providing we can document a recovery in ignition efficiency. Individuals 
or Vendors get
a chance to hose Us just 1 Time, No second chances. WE have worked thru 
many problems with outside suppliers , most times Everybody wins, fewer 
times , its a Wash Out. Being involved in the performance /racing Indusrty 
for 30+ years , we have a list of the Good Guys and The Bad Guys. Most of 
the bad guys aren't
in business any longer , anyway. What goes around , comes around , 
"Users  reveal 'themselves' and are avoided.
     There's a lot of question in my mind in totally removing the Opti , 
since the PCM  is "looking" for 4x - 360x pulses to determine injector 
sequencing.
I talked with the ElectroMotive Folks Today, Suppose I'll have to see how 
all this plays out. Thanks for the "Heads Up", Personally , I can't support any
product or service which we haven't tested in house and results verified. 
Advertising and Hype doesn't bring home any bacon. We'll be testing !
