So I've noticed a few things over the last couple months:

1. Anytime someone asks about pinning their secondaries, removing the butterflies, etc. the response is an onslaught of "Don't do it," "Your car needs it," "Removing it hurts performance" etc.. posts.

2. Many of the fastest, most tuned Contiques, are not using their IMRC's.

3. The same people telling others not to remove the IMRC are the owners of the cars with the IMRC removed.

4. The biggest reasons not to remove the IMRC/pin secondaries is that the computer will throw a CEL if the IMRC is gone and/or the air/fuel ratio will be wrong with the secondaries open all the time, causing lean conditions.


My questions:

1. Are the cars with the IMRC's removed all running full 3.0 oval port conversions, making the IMRC usless?

2. If it is indeed fully possible to rig a circuit to prevent a CEL while also preventing a lean condition, why not post a HOW-TO so that others can read what it takes and make the descion as to whether they want to risk screwing something up?

3. Is the solution to removing the IMRC getting an aftermarket chip and having it programmed to negate the computer's belief that an IMRC exists on the car?
