if l go the secondary actuator delete route...l more or less dont buy anything apart from plenum gaskets and l get a more reliable and simple fuel injection system....so
a couple of Qs
is it as simple as ripping out the vac plumbing, jumping the power and signal wiring from the primary injectors to the secondary injectors, tying open the secondary throttles
If not....then is there a 'step by step with pictures' available for this job....or can someone please send me a napkin schematic
what happens to the ECU outputs....codes, CEL other nasties that the ECU might do to the cars performance
are other engine data sensors affected which then provide bad signals to the ECU
But all in all....this sounds good to me....and Im a firm believer in KISS
(so why did l buy a ZR1 .....  )
Oh yes I know why  ...they go great....sound great....look great....and have lots of interesting moving parts (some of which it seems l will now remove)
Any additional help to the above would be appreciated

It IS as simple as removing the secondary vacuum pump associated hardware, actuators, and even the friggin throttle plates too!
You don't need to be jumping anything. I Just pluged in a Marc Hiabeck chip programed for cars sans secondary "system". Marc's chip also provides programming to better control the cooling fans, fix the high idle, optimize engine performance for higher operating temps, anti-backfire when using long tube headers. I'm VERY pleased with how the car performs now with the new calibration, as compared to stock. Smooth and very responsive, and no change in my fuel mileage...except maybe 1/2 a mile better w/ cruise control running! (28.5 mpg).
