Re: i am doing a secondary delete tomarrow for....
the person i am doing it for doesnt want to remove the plates or butterflies as he will have to pass ca smog once every 2 years . do we have to remove the actuators? and what does everyone use to keep them open /?

what if you leave the actuators for now and just hook them to manifold vacuum?
that will force them open to test out your chip function. Other than that, I almost want to suggest an old fashioned pull cable like on a choke for a carbed car. need to do it twice though. |

Also, you then need the chip programmed to run the secondary injectors "full" time and halve the primary dwell time (closed loop). The vacuum line is disconnected from the vacuum sensor to be exposed to atmospheric pressure which the new program reads as "normal" i.e., no codes are thrown sans vacuum. To return to stock, just snip the tie-wraps, swap the chip, restore the vacuum circuit and it's good to go. But, ya know...I would be tempted to see if it would pass emissions testing with the secondaries open. The stock tune at the low end of the rpm band, according to Marc, is a little "fat" anyway. So...it raises the question: Will it pass regardless of the secondary system being nulled? Just a thought. As for the "choke cable" scenario, that is intriguing! An external actuator, if you will, would eliminate a plenum pull. Tho pulling the plenum is a snap, (once you do it a couple times to establish a routine) the fewer times those connectors are pulled apart and reinstalled...the better, I recon! P.
