I am using an ECM out of a 2005 LS2 GTO, fairly certain it is an E40.  Using HPTuners I am able to set the idle below 800 rpms.  With HPtuners there is a table titled "Idle Speed Min"  which allow one to lower the idle rpms below 800.  This table was not visible in all versions of HPTuners.

Normally my idle is set at 800 because I run a/c in the summer.  I lowered my idle this morning to verify. The engine average idle speed was 722 rpms, although I set it for 650. I probably would need to adjust idle airflow to obtain 650.

I believe 05-06 GTOs are LS2 E40 ECMs.

In EFILive B1821 is desired idle air speed. No matter how low I set desired rpm, when scanning, target idle PID will not display lower than 800 rpm? I can get the car to idle lower but if desired is still displaying 800 then the ECM will compensate with spark and air trying to hit desired. I want to believe that its possible to go lower because the trailblazer SS is also an ls2 e40 ecm and its desired idle speeds are below 800?


Well to dial in the MAF (via HPTuners) I use the same old histrogram I used on my 0411 PCM. As for tuning the dreaded E40 virtual VE I use Bluecats VE software. It works great but is time consuming.


This is all still done on HPTuners V2.24
I refuse to upgrade to their newest version. I dont like change.

Change always sucks especially when your still learning the ropes or just learned the ropes. Everything is getting so technical, its great if your up to date and know how everything works but sucks so much when you don't.

If you don't mind posting them or PMing me, I'd be interested to see the tunes of those who have an e40 ECM setup.

Hello groovin,

There are 2 tables in HPT that address idle rpms.

One labeled, "Target Idle Speed" and the other is "Idle Speed Min".  It is the 2nd table that is not always displayed....depending on the version of HPT, that I changed yesterday.  The "Idle Speed Min" table seems to override the other table when the engine (coolant temp) is warmed up.

Perhaps EFI live has a similar table.

Shit, you are right. My mistake. I am only E38 versed, I assumed E40 was the same.

I just went through everything and even in the custom operating system the only controls for idle on the e40 ecm for EFILive is the table I mentioned, B1821. EFILive didn't give as much love to the short runned e40 ecm as HPTuners did.

I got some montego blue mudguards for the the MB FD to replace the already installed black ones. The plan was to paint them BMW mineral white metallic and put them on the white FD but I wanted to see how it would look on the car as is, black. I think I like it, it blends nicely with the rear diffuser. Do you think I should keep them black or paint to match? I found some pictures of a similar build with paint matched mudguards for comparison.

If you havenít noticed yet I also installed a Honda element antenna using halfspecs adapter.

It seems itís going to be a while before pettit has some steering column gauge pods made so in the mean time I modified my stock one and mounted the wideband.

Out doing wedding errands, came back and found the lighting was too nice to pass up on a few photos. Then had dinner with my brother who insisted on doing side by side photos. Since I needed some gas I said just follow me there and we can do a quick shoot. Quick amateur editing via google photos.

Lol, are you referring to the golf TDI? I bought it that way and love the carefree driving that resulted from it so I decided to leave it as is. 3" lift super tall tires = no f*cks given about road conditions. Who knows, maybe I'll take a page out of GC3s miata build and bring it another level up with some off road tires and accessories.  :D

I didn't realize it was actually raised.  I was just referring to the drastic height difference compared to the FD.  ;)

Yeah, the previous owner was from Utah and said the road conditions there were terrible. So bad he turned the golf into the 4x4 you see now. Even so as you said, the height difference is pretty crazy. Even next to my bros 135i there is a clear height difference and the 135i is considered a small car in the modern market. When the FD is park in a plaza parking lot it sticks out so much and makes it easy to spot which is awesome and concerning.

I'm still leaning towards paint matching them but was curious how it looked black and to my surprise it doesn't look bad.

How do you like the m235i? Have you had any issues with the fuel pump? The M2 is looking pretty nice. I'm just sad that despite being as small as it is they are pretty damn heavy.

Absolutely love the M235i, much more than I thought I would.  It is a manual which was a huge selling point for me.  Never knew 300 horsepower could feel so strong either.  I thought I was going to be tempted to go crazy with the boost, but I don't want for any more power strangely.  It is a very well optimized package.  Just put an exhaust on it which cured my #1 complaint which is that it was silent inside and nearly silent even with the windows down.  I was able to disable the fake stereo engine noise with the exhaust and the car sounds phenomenal.

Only other complaints are that it has an open differential not being a true M car, and the gas tank is a bit small for the economy the manual gets (and my heavy foot).

No mechanical issues.  Wasn't aware of any fuel pump problems.  Car is still under warranty and has the maintenance plan so I'm not too worried, at least until mid 2020 lol.  My old miata was taking too much time away from the Rx7 and I had to get something that I could use and abuse and take it to someone else to deal with.

The M2 is not really a worthwhile upgrade over the M235i.  The new M2 competition appears to be a damn good car and still comes in a manual.  In 2-3 years I may have to trade in.
