LM002 RHD Rolling restoration.. will be updated regularly

Actually You may be correct.
It is a typo. 200 and 290 is too close on the keyboard.

 

Thanks Chris, Taz,

The LM is still running a bit rich, we will have to do another fuel trim.

I share this restoration/modification experience in this forum so that owners/future owners can duplicate this and improve on what I had done. Hopefully the car will be much more reliable than factory standard.

Cheers,
Taffy

 

Problem no 1 :
=========

When hot, car does not want to start.
We check from the ECU, the Magnetic Spaghetti ignition trigger at HOME (IIRC it is part no SEN8D) did not want to read.
The occurence is getting more and more often.
Our air gap is about 0.9mm which is between the factory suggested range of 0.5-1.0mm
This is a brand new ignition sensor. Maybe it is also getting weak (??)
We also do know know the OEM voltage on this sensor @100rpm, 300rpm, 500rpm, etc. We are using the common setting used in other cars, about 0.25v @100rpm.

Solution : make the gap smaller down to 0.5mm by scraping the base

Problem no 2 :
=========

When we were adjusting the throttle body on Saturday, we did not install the restrictive intake yet, thus the left and right cylinder bank is having the same airflow straight from the front.
After we install everything, the left cylinder bank temp drops compared to the right bank due to bad airflow in the carbon intake (180 degree U-turn for the left bank) while the right bank is somewhat better. This is basic design flaw of the LM and happens of the RHD model. On the LHD model it is vice versa, the right bank gets worse airflow compared to the left bank. If You own LHD LM002 You may want to check each one of Your header temp using infra red temp gun.
Thanks to the 12 EGT sensors, no guesswork on this one. This is just a matter of opening more air to the left bank.

If I want to get it correct, ditch the cooking pot air filter, use conical shape air filter on each end of the intake. Better airflow, power and throttle response. I think I've seen an LM modified like this somewhere on the internet. Should be good for daily driving. Sounds meaner too. Use the cooking pot only for car shows.

 

These 12 babies save us so much time and minimizing guesswork.

Roughly like this :

On the LHD LM the right cylinder bank is gasping for air, on mine it is vice versa.

Better solution but engine bay will look a bit ricey

A bit OT, has anyone download this on their Forza Horizon 2 yet?

The dashboard is even better than the real car !
Now I can read my speedometer

Better use oval shape cone filters, place them horizontally, make a new fiberglass hood and cut a hole for Cold Air Intake.

I know this is a bit too extreme but it is just an idea

Tony, have You ever listened to the engine without the restrictive filter while opening the hood and manually opening the throttle with Your hands ? The sound is deafening. Agus can vouch for that.
The throttle response is also much much better.

The Countach and LM basically use the same engine thus the factory give the same 450 hp rating. I bet they did that only on the dyno. Once the engine is fully dressed in the LM I suspect the power drops 30-40 hp. The engine is literally suffocating.

 

My silly drawing goes something like this :

New bonnet Tony, make a copy in the same fiberglass then make a hole.

 

Sorry wrong pic... That is a Countach engine

 

Good idea
