With my lead foot syndrome, I thought I was bound to pop a piston soon. I'm surprised that this regal has lasted this far (has 115k on the OD, had it since 20k). Thanks for the relief

On the topic of O2 sensors, I think I might have a different problem at hand here... Mvolts are pretty lean at WOT. Luckily there is no KR.

I am noticing that my injector duty...

I guess the 02 values weren't all over the place at idle once the car was at operating temp. As you can see below, the fluctuations aren't as rough, but once I accelerate things go back to normal. So...

Hey now, this old boat has smoked plenty of v8's :cool:


Sweet, I did not know that. Yeah this Regal is definitely not light at all. Thanks

When I am in WOT I can hardly touch the .92 g/cyl column. Is this because of the Northstar throttle body? Should I be concerned? Any input would be appreciated.

I was doing my morning scan on the way to work as it is getting colder outside and as I was waiting for the light to turn green I see my front o2 sensor going a little crazy. Is this normal? I mean I...

Firstly I want to give you both a big THANKS for the help. Sometimes I feel so lost with this stuff that I just want to throw in the towel.



Yeah that's what I thought too that the MAF sensor...

First don't look at the max KR. Concentrate on the average. Looks normal to me man. Also I don't know where you're from but 86*F is pretty darn warm where I come from.

I did not know that. I know for the 3800's that the knock sensor will "attack" the knock retard before you even get the chance to even see it (Which is pretty smart coming from a considerably "dumb"...

The 3.6 LFX engine might be different than the 3.8, but for me KR (Knock Retard) is not stored just read and corrected as far as I know.



Heat is a significant contributing factor with KR....

Not too long ago I upgraded my stock GTP injectors to a set of Bosch 42.5's (Part #9202100 / 0280155968). After doing a ton of research I realized that everyone has their different ways to adjust for...

Ok great thanks. Yeah I use 93 Octane. I guess before anything I should figure out why I can't read my MAP sensor.

I hate doing another "Please help me" thread but I'm completely stuck here and I would highly appreciate some expertise. I recently added 42 lb injectors "Green Giants" from stock, a short stack...

Firstly I want to say thanks for the reply. Ok so my normal operating temp is around 184*. My stock setting was to enable closed loop at 43*.

Regarding my other post where I had my closed loop...

Hey Guys,
Thanks to Mr. Russ K I have gotten my LTFT's to 0 at WOT (besides today since it is ~10* warmer outside)!! Also I have to mention how much faster the Ghetto Cruiser feels now too :cool:...

Hey Everyone,

For some reason whenever I try to change the Climate Control Override to disable, it automatically changes my Decay Profile under Accel Enrich cell 13 to 0. I tried to clear my...

A little update...

After some logging in the scanner I noticed that the front o2 remained pretty stable at idle, but when I give it a little gas the O2 starts cycling like normal (I think this is...

Ok after flashing the pcm with the stock settings, afr was looking great at about 13ish but when I gave it just a little gas the car stalled. After the second try to start, I get back to an AFR of...

Well thank you for your time and the great input :)

From now on I will just maf tune and not screw anything else up.

Hey Guys,

48 hours deep into tuning and I have already ran into some issues go figure.... I recently added headers (boy how fun that was) and I figured I shall tune the Regal. So I do some maf...
