[LS2] Installing OTR without MAFless tune?

[one_and_only2004]

What sort of bad things happen if you install a MAFless OTR onto a car that hasn't been tuned for it? I more or less want to just fit mine up before I go to the tuner.

Well your car will run like **** EDIT>> (limp home mode) << EDIT because it need's the maf to tell it airflow an what not, you can get OTR's that run the maf as i had one on my ss before i got a ramjet an mafles tune.
EDIT: I just remembered the ramjet can be ordered to run a maf or mafless.

I was more or less just wondering if my duspeed OTR could be put on before I go to he tuner that's all.
So it'll run like ****, but it won't explode?

It wont run, your car requires air flow through the Maf as it is a vital sensor for the engine to operate.

I found this out the other day. My car started then died within 2 seconds.

Oh well thanks for clearing that up for me, looks like I'll leave it to those guys to fit. I'd just read that when the MAF is disconnected it goes into a limp mode using the MAP sensor to work things out - obviously this is wrong!

Unplug your MAF and find out.

It should go into limp home mode, They did this so if the maf failed you could still get it to a safe place.

excactly.
It will still drive, and drive reasonably well.

Different engine i know, but my l67 runs with no maf, just feels rough and the engine light comes on. I found this out when I forgot to plug it in one day.

The only thing is I wouldnt give it a hard time in case it leans out
