Hey guys, I contacted Mike about getting a standard tune PCM from Milzy Motorsports. He said based on the simple mods I've done (FWI and u-bend delete) the standard will be a better choice than the stage 1. So before I buy it, will I need to buy a colder range of spark plugs and if so what range would that be? I found out that since I bought my car it has been running the 180* T-stat which I discovered is not stock temp. Will I need to change anything else? And if anyone else has gone this route and could share their experience with the change, that would be a nice helping hand. TIA

Nothing else is needed for a base tune from Milzy. Just let them know about the 180 t-stat so he can adjust the cooling fans to take full advantage of the extra cooling. You might have him disable the rear O2 sensor too incase you decide to do extra mods later on and won't need another reflash.

Colder plugs are really only needed with modding a L67 or if you have a heavily modded L36

Alright, thanks a bunch ZSPOT Very Happy. I don't plan to do any further performance mods (at least for now) to this car after the PCM so I can start a budget to buy and mod an SS. I'll mention the 180* t stat though.

Thanks Pitch Black SS. Guess I'll keep my stock plugs until it's time for a tune up. I have the furthest thing from a heavily modded engine Laughing

Last quick question: a relearn will be needed right?

even when you do the tune up, put new stock plugs back in along with new stock wires

more than likely a security relearn would be needed. Sometimes a CASE learn needs to be done. Dealership or a good shop can do this

It's covered Wink

Quote:

Removal of all speed limiters
Higher shift points
Higher rev limiter
Shift firmness adjusted
Ignition timing advanced
Cooling fan control (180)
Cooling fans on at key-off for 180 seconds
Rear O2 Bank code removed
Etc.

At request:

Codes removed
Torque management
A/F adjustments

I would assume anything "at request" will add to the price.

Yeah, I have AC Delco in mind for the replacement for plugs, wires and fuel filter as well as some other things. I try to use Delco whenever possible.

The relearn is the procedure that requires cycling the key to the "ON" position for eleven minutes then off for 30 seconds for a total of 3 times, right?

I spoke with Mike and he said he'll program the PCM to lock up the torque converter at a higher speed (I'm thinking maybe around 45 mph instead of the pre-programmed 41 at low throttle angle/load) so I can have a slightly lower cruising RPM and gain some fuel economy. Would there be any potential problems with doing this? If any complications arise then I'll stick to the regular setting and not have that part of the request tuned

Id stick with the stock setting, these transmissions are pretty fragile and I wouldnt mess with them

Security relearn is the ON / OFF key thing

CASE learn requires a plug in unit. Either a Tech2 from the dealership or equivalent device from an independent shop. Some need it, some dont. My SS didnt

What's all this?
Security relearn?
CASE?

I'll need to perform one or both of these if I replace the PCM?

Alright, sticking with the stock setting would keep everything simple. Guess I won't be making that request, thanks for the heads up on that, PBSS

I read something about this, not entirely sure how much of it I remember so don't quote me on it: Security Relearn is the procedure that the PCM takes to relearn the code that the key sends it through a resistance embedded code that is transmitted when the key is inserted in the ignition switch. These steps are taken so the PCM can learn the code and accept it, allowing the car to start.
I also read what CASE is but I can't remember the details as well as I can for the relearn
Security relearn will need to be done, I don't know if you'll have to do a CASE or "Crankshaft Angle Sensing Error" to be honest, but Pitch Black SS says his car didn't, maybe we won't

If you send in YOUR PCM to be tuned, neither of these are needed. But swapping in a different PCM, then yes on the security, maybe on the CASE

Crap... this is my daily. Can't be without it for a few days.
Hopefully no CASE is needed... Neutral

One last question before I place the order: I'm aware that the engine will be running cooler and will benefit more now bc the fans will run at t stat rated temp of 180, but is it known for there to be knock due to the advanced timing in hot weather or is the advance not enough for me to have to worry about that?

In all the years I've been here, I've never heard of anyone having a problem with Mike's tunes. I may have missed something over the years, but if there was, it's rare as hell.
