The last "tuneup" was simply an ignition re-hash of plugs and wires with lots of contact cleaning and boot grease, which helped running quality considerably. Still haven't verified any of the vacuum components, but I just got my first good look at the tranny's pressure modulator today. Never cleaned a MAF sensor, gonna look into that as soon as I'm done with this post. Air filter was replaced a month before it sat down, and passed my inspection when I popped it out. Don't know how many fuel filters I have, probably need to go searching for those too.

I will definitely be considering your offer for a $40 cable, please hold that for me until I can tell you how the financial situation is working out. I am currently looking around for what I must have in order to read and log data from my specific vehicle, and the ability to monitor current conditions is very important to me - but the support forum is giving me the idea that my v4.14 won't be able to do that? Should I look for a different version?


I'm a bit excited about a cooler too, been looking at the front of my vehicle for placement and at the seal between electric fans and current exchanger. Considering installing a permanent trans temp gauge, but I'm not sure where an appropriate plumbing point would be.

I used TunerPro to scan everything in my car with that ALDL cable. You'll need an XDF definition file, which I should have on my laptop somewhere. I'll get ahold of Robert so he can help you out in this thread.

There's only one fuel filter, directly in front of your fuel tank.

You can buy an aerosol can of MAF cleaner at any auto store. I would highly recommend you use it after every oil change. It will make an immense difference.

I have my eyes on a smaller Hayden 404 aux fluid cooler (7.5" x 15.875" x 0.75") and I'm wondering how many of you have plumbed one of these in with no new hard lines. It sounds like a cheep approach, but that's cause I'm cheap. Ran it by the parents and they OK'd a dip into my college refund money for all this stuff. Now I'm wondering how to hook up a fluid cooler without losing too much fluid.

Looked into what style of MAF sensor I have equipped, and it looks to be a fairly robust model (replaced by A1 Cardone) - I assume it can take the force of propellant/solvent cleaning? I will be doing this as soon as the weekend rolls around if the local VatoZone / O'Reilley's / NAPA / Federated carries it.

As for definitions, this is what I found:
$5B - 16183247 - 94-95 Series 1 3.8L (L27) and 94-95 Series 3.8L SC (L67, ECU# omitted)
$5B6 - 16183247 - 1995 Series 2 3800 (all)
$5B7 - 16183247 - 94-95 Series 1 3800 and Series 1 3800 Supercharged

$5B seems to include both binary and ALDL definition support, but is only for TunerPro v5. Downloaded that just now so that I'm equipped if necessary. $5B6 also includes both binary and ALDL definition support for v4. The last $5B7 series only contains ALDL definition, so I'm guessing if I have a "Series 1" 3800, I'll need to use $5B and then $5B6 if I have a "Series 2."

Looks like you have it all figured out! I plumbed mine in using the rubber hoses that it came with, though I did have to buy the fittings. They should have the proper fittings at the store.

That's correct.

Actually, still don't know if I have a Series 1 or Series 2 v3800. Does it really even matter?

After looking at my radiator I'm convinced that I should find a way to mount the aux cooler high, just so it's in direct ram air from the front vs. air dam redirection from the bottom. The existing cooling lines run hard until halfway across the radiator, where they turn to rubber. Will the order in which it's plumbed matter much?

I'll probably get back to you about the cable via PM, but only after the cooler has been sorted out. Again, thanks for the help.

If its a 95, its a series 1. Trust me. Regals got the Series 1 in 95, and Bonnevilles got the Series 2.

You run the fluid through the radiator first, then through the transmission cooler. To figure out which hose to use, start up your car and grab both lines. The one that's cooler will be the return hose. You'll need to feed that into the transmission cooler, and then from the transmission cooler back to the return hose.

thought bonnes got the series two in 96

IIRC, it was the Series 1 L67 in the 1995 SSEi and the Series 2 L36 in the 1995 SSE, and the Series 2 L67 in the 1996 SSEi. I don't think any 1995 Bonnevilles got the Series 1 L27.

hu okay then makes sense
