Enjoying watching your build and getting ideas for my car, 2008 S240 which I run in TT3. Like you, I use AIM data which I like very much. My question is this: I added an oil pressure sensor using a T fitting with the stock oil pressure switch. MXL2 dash reads 0 engine off and 1-2 psi engine running. Sent the sensor and the dash back to Josh at AIM, both check out. Had my local AIM dealer check the install, we can't figure out why this won't work. Any ideas?
I suppose it's possible that you only have 1-2PSI oil pressure!-eek-

Are you finding that the pressure comes up with RPM?

Have you verified the oil pressure with a mechanical gauge?

Additionally, are you mounting the sensor right on the block or from a hose? The sensor should not be mounted right on the motor, but rather remote mounted on the firewall. The vibration from the motor can cause them to give odd readings and/or fail early....

Hope that helps,

Phil

No, pressure does not change with rpm. I mounted sensor on the head with the stock pressure switch. I'll try mounting on firewall. Thanks for your help.

Ah. Well, there's your problem. The sensor on the head is just a VVL verification sensor. It only receives pressure when the "big cam" is engaged. The proper location is just above the oil filter on the block. You'll find another pressure switch there. You can tee off it. The thread is 1/8 BSP taper.

Phil,
Thanks for putting me on the right track, got the oil pressure display working now. Next I want to install MAP sensor. Where should I tap into manifold pressure?

So I sold my precious race car a couple weeks ago... Kids, family, etc, etc... Time for a change... and then there are the Evoras too! :)

The new owner posted up his comments after getting it to the track for the first time.... His most precise comment to describe my old car, "This car was insanely fast, requires 100% concentration and the harder your push the more it asks for."

...Going to miss that chapter!...

So as some of you may know, I have owned and raced my 2005 Lotus Elise since 2012 and just built it to competitive @ SSM level (FYI it is for sale if anyone is interested). While the engine was being built by Phil and team at BoE, Phil decided to sell his full race Elise and unbelievably I won the auction and picked it up Labor day weekend. Since then I have been working on selling mine and getting my tow rig repaired so Sunday was my first day actually starting it up and running it. Keep in mind this is Florida and it was 100 degrees outside and sunny so temps are hard to keep down so I only was getting 5 flying laps per session.

I went into this event with the mind set that this is a new car to me, double the HP from the old build of mine, mechanical brake bias system with no ABS, sequential transmission with no LSD and all kinds of aero, so my wish was just to drive 7/10th, learn the car, have fun, don't blow it up and don't wreck it. Phil has owned this car from new, built it from the ground up to be the beast it is today and it performed exactly as advertised. This car was insanely fast, requires 100% concentration and the harder your push the more it asks for.

I ran at The FIRM, which is semi local 1.6 mile road course, that in my old Lotus on the Rev400 setup, my personal best was 1:18.2. This is after hundreds of laps on this course and hundreds of hours in my car. Yesterday in the new to me Lotus from Phil, this car ran a 1:15.492 out of the gate (although apparently my video feed had issues the entire session). This was not only almost 3 second faster but I wasn't even touching the limits of what this car can do. I could easily see 1:13s in it on cooler days with more seat time. I was also informed later from the guys at the track this could be the fastest non open wheel lap set at this track.

Just wanted to share the experience that I had yesterday grinning from ear to ear, and also say what many of us know that there is no substitute for experience and dedication to a chassis like Phil and BoE have to get the most out of your car. This video is from my second fastest lap that the video recorded at 1:16.206. Enjoy the glorious sounds from this Lotus I now call "End Game".

Phil don't beat me up to much on driving this monster, I know I could be braking much later and using every inch of the track :)
