I've talked to someone very knowledgeable on this ECM and after looking at my OS/Tune in HPT he's determined it is doable. Now to wire in the sensor. Will keep you guys posted on how it goes.

I just ran across the fact that the e67 ECM can run a flex fuel sensor and calculate fueling and timing based on that sensor's input. I would love to use that feature in my 2007 Sky with the LE5 but...

Good read.

Dr. Noops, the LE5 in the Sky is set to 7K redline from the factory. I don't know what the difference is between that and this gentleman's 2.4 ECO (if any...) but it does like to rev. ...

Thanks Dr. Nopps.

Well, the mid to high end of the tune seems to be FUNCTIONING well but the trims look horrible and the idle is demonic.

I found my car is fine running a leaner AF. I'm at...

JMsquared, thank you for asking these questions. I'm working on a 2.4 LE5 with a K04 Turbo off an LNF and I've learned a lot just from this discussion. I would like more information on your last,...

Interesting. I've compared by tune to others in the repository and they seem to be running more timing than mine so I figured I should be able to up it some and they're running bigger turbos.

I...

I have a 2007 Saturn Sky with the LE5 (2.4 NA) stock. I have added the K04 turbo off the LNF to the car with a mechanical boost controller, stock LNF cat downpipe, 60# injectors and a 2-bar MAP....

The GXP is an LNF.

CAIs really don't do much for the LNF on the Kappas. If you have to have one, I'd suggest the GMPP.

Is there anything like this for the LE5? I'm trying to understand how all this works (New to all this in so many ways) and any kind of help would be nice. I got my fueling down but now, when I shift...

I know this is a bit of an outdated thread at 2 weeks, but, have you checked for anything rattling around in the engine bay? GPs are horrible with part throttle false KR.

Also, those seem like...

The problem is pretty simple, whenever I push the clutch pedal in and let the engine RPMs come down, they dip real low, to like 400 rpm, and the car feels like it is going to stall. Then they...

I don't know what MAF you're using but the stock MAF that is in the Sky LE5 is really sensitive to airflow disruptions. If you're not getting smooth flow over the MAF it could cause issues with it...

No problem. I know I always hate it when someone posts an issue like this and doesn't update the resolution they found for it. LOL I wasn't going to be THAT guy.

Just to follow up on this in case anyone is interested, my issue with the hiccup eventually turned out to be a failing ECU. I got a P0606 error code and the symptoms began to get worse. Poor running...

Interesting.

I just installed a K04 turbo off an LNF on my LE5 and am having similar issues. I get P0121, P0300 and (can't remember the code) fuel bank 1 lean. The car is on a basic tune and my...

Gotcha...I think. Really need to search on how this ECM logic works...trying to wrap my head around this and just have bits and pieces. Feeling very dumb at the moment.

EDIT: Seriously, if anyone...

Maybe I missed something but weren't we originally talking about MAF sensor ranges and now have moved on to MAP sensors? I didn't pick up the transition.

Coming from the L67 world, I believe we ran the MAF all the time as well. I believe we would reference the MAF readings (in conjunction with 3-bar MAP readings) at WOT to check for belt slip on my...

No worries about hijacking the thread. Through your discussion I'm getting a better understanding of ECM logic. Better...as in I'm looking at the peak of an iceberg with a magnifying glass. LOL
...

I think the issue is Patooyee that he meant to say he shuts off the MAF after 2200 rpm. In my (VERY VERY) limited knowledge of how all this works, that statement makes more sense to me than saying...

I would love to go 3 bar but right now won't be running more than 12 psi until I can reduce compression. Have no idea how much boost on what turbo I'll need in the future to get the power level I...

I must say that's one thing I never looked into with my GTP. If no one here can help you, see if you can get ahold of Paul from PRJ Performance. I know he is kind of out of the business end these...

Learning so much here. Now then, with this information, this is the 2-bar that will work for an LE5 2.4 boosted application, yes?

Now I just need to figure out what to do with the vent line coming...

So many damn numbers.

12592016 is used just for MAP reading. 12592017 is your intake temp reading and a MAP reference. I'm not sure if the LNF in the Sky uses 12592017 as a MAP reference too. I...

I believe the 2007 Redlines came with a 2.5 bar but later years came with a 2.7. At least that's what I'm hearing (I'm a 2.4...we only got the 1 bar). I know it is more than a 2 bar as the stock...
