Back in december I did a leak down and compression on my W2 416 and found two leaky valves. Upon disassembly I found a few things that needed attention, it had a bad exhaust seat, a bad roller lifter, and a bad timing chain. So I am having hardened seats put in the old W2s, swapping another set of roller lifters that was on the list anyways, and we replaced the timing chain. This time I added a slinger and drilled the proper bolt to get oil from the valley, neither had been done(I guess the bolt slipped past us on assembly). I also cleaned up some mismatch in the ports from when I did the tunnel ram swap. I am not expecting much ET gain but hopefully a little.

The biggest problem is I got lazy and didn't get to working on it until last month. So while I am waiting on the heads to get finished up I added a front wheel speed sensor to my MS3 fuel injection. This will work with the 16 tooth reluctor on the pinion for traction control and getting exact tire slip % numbers. I don't need traction control at this level since my car is 100% stuck most of the time but I figured it would be fun to play with on the street. I added an extra hall effect sensor I had onto the passenger front wheel to read the bolts that hold the rotor to the hub, this give it 6 points of resolution. I have wanted to mess with this ever since they released this feature several years ago, but I am just now getting around to it.

The bottom gauge there shows MPH on the front wheel, that clicking is a piece of safety wire I had to adjust.

This was also the first time I really played around with the Bluetooth I added to the ECU, my laptop didn't have any trouble connecting anywhere in my 2 car garage. It will be nice not worrying about a USB cable. Now I can download data logs from my folding chair instead of baking in the car a few minutes longer.

Very cool updates and upgrades! Will be interested to hear how it all works out.

Still no cylinder heads so I did some more busy work in the garage. I bought a flex fuel sensor awhile back so I added that into my return line and wired it up. It gives ethanol percentage as well as fuel temperature. I was more interested in the fuel temperature because that has been an issue before on long drives. In the future I would like to add a few more points of compression(currently 10:1) or something like a Turbocharger so E85 capability will have a place one day hopefully, I have enough fuel pump and injector to use it now so I might try it just to see if it is better than the 91 octane I run now.
