Eliminating the secondaries
 

I am going to remove the plenum on my 91 to replace the injectors. While it is off, I am going to install Jerry's new and improved fuel pressure regulator. I also want to remove all the secondary stuff to make the car simpler. I know Marc has a DVD which describes the removal process but I am wondering if there is a DVD that shows the secondary removal process. Dynomite describes the process with some pictures but I would really like some more detailed information. Perhaps once the plenum is off, his descriptions will make more sense to me. Thanks in advance, Perry

No videos that I am aware of. Too many old guys here (till now) that can?t handle a smart phone. The references you mention are very good though. Don?t forget you will need a Haibeck chip to handle the secondary delete in the ECM. Member Domenic Sorresso (Xfirez51) also does them. I have mine deleted, Dominic did the tune. Runs seamlessly! Nice not to have the secondary system issues worry.

I still have my secondaries.. they still work fine

Ditto.... Mine are working as theyre supposed to as well. Im not sure why so many guys dislike one of the features that makes the LT-5 special... :o

The simplest thing to do is just tie wrap them open and modify the calibration. That was my first step, then I removed throttle plates and kept throttle shafts in open position again w tie wrap. When I had heads ported. We took out everything.

Get rid of them if you are in there.

Just because you had a screw loose (LOL) doesn't mean we all do :-D

However, while apart that is a good thing to inspect

Unfortunately 2... One per head

Mine are still working, with the MS-Pro (Megasquirt) ECU.

I gave my car to them (DIYAutoTune) a few years ago when they were working on the LT-5 tune. Before I gave my car to them I had disabled my secondaries. They asked me to put it back together, which I did, because they wanted to control the secondaries.

I realize this is apples to oranges, but my car made more horsepower when they were done.

If I could figure out a nice dash layout with aftermarket gauges I think it would work well with the DIY Autotune set up
