I'm fitting MSD;'s closed-loop fuelling software, and will probably be fitting an Innovate wideband lambda controller. I read somewhere that the sensor needs to be a good way from the turbo to prevent heat damage.

I'm looking for somewhere safer to put the sensor - had a look under the car tonight and came up with this:





If you can't figure it out, its the outside of the bend to the rear, below the steering shaft and beside the front diff.

Is this any good? i.e. far enough from the turbo, unlikely to get knocked etc?

Cheers all!

**stu posting**

At the top just before she bends downwards will be just fine pal.. remember, the tip sits at 800C at all times anyway...

A lot of the "Heat damage" you hear about is garbage.. lol

Remember, keep her above teh horizontal plane ideally.

 

Neil, I prefer welding stood up rather than laid under a car so as it's me doing it going where stu says!!

lol
mind you I hope we can get the drill in at the top of the bend the bulkhead is a bit close

Good enough for me boss

So, just after the turbo-downpipe joint, on top of the downpipe?

Another quicky for you... Is it possible in your opinion to detect the effect of one cylinder leaning when you are reading the combined AFR from 4 pots?

I guess what I'm really asking is "is it worthwhile buying an AFR meter". I know it caught your failing fuel pump, but that would give a bigger increase in AFR than what I'm getting at

Cheers!

Neil.

 

You can Steve, we do em everyday pal

 

Ste - the turbo will be offski, so I'll take the DP off to drill it and weld

Well guessed about who will be welding it though!

Neil.

 

No Neil, if one pot leans off you wont see it on an AFR gauge, in fact, the only real way is with 4 independant EGT sensors (on a 4cyl of course) or 4 independant AFR meters.

However, it will spot all teh more common failures, as one leaning off is actually very rare.

Fuel regs
Fuel lines
Fuel filters
Fuel pumps
Fuel pump wiring
Ecu voltage
mapping

All teh above will give a global lean off, which the AFR meter will spot at once.

 

Cheers Stu.

Sounds like the Innovate is a good idea then

I'm thinking of knocking something up to give a warning under an on boost and high AFR condition so I won't have to rely fully on reading the gauge all the fookin time

I've got a few more questions relating to fitting the kit / setting up etc - can I give you a quick call tomorrow afty?

Cheers again

Neil.

 

I "think" it already does it pal, maybe worth a post to ask?

Call me when you feel like pal.

 

I'll mail them and get it straight from the horses mouth I think

Speak soon Cheers for the help!

Neil.

 

Neil,

seems like a good bit of kit i have spent a lot of time looking at
the lm1 innovate meter, are you going to also use the aux lma-3 box
with the lm1, so you can have inputs for rpm, boost, throttle% etc
logged. and as nicole above sensor position before the cat if applicable
and DO NOT install the bung below the 3,oclock or 9,oclock position.
condensation can form in the exhaust pipe and permanently damage
the sensor, 6,oclock is the worst position to mount the sensor.


DAVE R.

 

Ahhh, so that's the reason

I'll have a look at the lma-3 - cheers matey

Neil.
