Where has ROTUS been? Out and about.
ROTUS was licensed this year, which has been great. I have been able to drive the car around once in a while, and not have to wait for the track. Only real issue on the streets is how loud the car is, this is even an issue at the track.
I have sourced some material to re-pack the mufflers with, just have not finished this up yet. Was going to use stainless steel scrubble, yet I understand it gets brittle through heat cycling, so have gone another direction. Non-ceramic Kiln insulation. Good to 2300 degree, great sound deadening quality, and non-carcinogenic (this was an issue in shopping for this stuff). Hope to get this done in the next couple of weeks.
The biggest challenge I have been working on is returning to the Megasquirt fuel injection. When it is on, it is great! I like even better than the weber IDA. When it is off, it is crazy making.
Last year I burned up the injector driver on my Megasquirt, so I set it aside and went back to the Carb. Asked the guys at Spitfire EFI to build me a MS2 v3 with a rotary ignition set up. And they did a great job for me. With LOTS and LOTS of coaching (thank you VERY much Chuck) the car is running pretty good. Still working out ground issues and a voltage spikes/drops. As a result, the car is only tuned to 7,500 RPM.A bit of a pay off!
Sunday was an autocross with my club. So, I went to the track running on the battery (no alternator). Trailered ROTUS to the track, ran on the battery while I was there. I think the car was still cold on the first run and it was really running poorly. 2nd through 5th runs and it was doing GREAT! Wow, it was so fast I did not even have a chance to get scared. 1st and 2nd and in seconds doing 60 mph, wow. Then hitting the corner on warm slicks, intense!
Now, I am feeling re-energized. I am going through the wiring harness step by step looking for anything that could be an issue. Checking grounds, and will change the ground on the O2 sensor. Looking at charging issues and the connections involved in powering the MS unit.
I big lesson I have learned from Chuck, there is a big difference between electrical and electronic…I am learning about this daily.
Thanks again ~ JEB and ROTUS
