I'd love to hear about your MoTeC experience. There are lots of coils that MoTec supports directly but the main data you need to write a custom calibration is dwell time vs voltage. If you don't have ...

I went through this same thought exercise. Looked into various race seats, talked to a couple seat manufacturers. In the end I made my own poured foam seat. Actually, I made two. 🙂 The first one was ....

Thanks guys. Not ever having seen the 54L tank -- I figured everybody had the same tank.

Here are some recent photos. I've been heads-down with wires, connectors, and sheathing for several weeks. The wheel speed sensors are nearly a bolt-in (I had to turn the hubs about 0.2mm to get a pro...

Hi Dan! No. The M1 requires an extra box (an ignitor) to run the Hayabusa stick coils. I searched long and hard to find these Bosch units. They are actually in Bosch's motorsports catalog, so the cali...

The fuel pump is back in the car, and I tested the low fuel warning "system" (aka light, 🙂 ). Works great. It might just be a bit too late... the warning comes on with about a liter left. Hopefully, a...

I agree... it shouldn't be a big problem. It's just that the MXL and the MoTeC ECU may not play that well together. Time will tell.

What will be cool is if I can run this Alarm through the ECU, and get it on the CAN bus along with the fuel consumption number. Then I can put it all on the dash display, rather than have a separate l...

Over the past couple of days, I've been getting my fuel pump ready to go back in the car. One of the things I find most annoying about my SR8 is the lack of a fuel gauge. My understanding is that even...

Today I finished the pedal part of the DBW setup. I used a part Tilton sells to convert their 3 pedal series to DBW, and adapted it to the Radical. Like the actuator, the DBW uses the Penny+Giles TPS ...

Good question Graeme. The new design using a linkage rod between the actuator and the throttles is much more tolerant of minor actuator movement relative to the throttle bodies than my original direct...

Jenvey wanted me to change the design of the DBW -- they didn't like how I'd made the actuator driver the throttle directly, rather than through a linkage. I'm a big believer in learning from experts,...

While I wait for some final parts on the DBW actuator, I've turned my attention to the PWM control of the fuel pump. The OEM design is to use a return line with a mechanical regulator, and while it's ...

The sensor calibrations have all been done -- that's just a matter of patience and mastering the M1 Tune software to enter them all. The MoTeC is like a late model manufacturer ECU -- there are no fu...

My trial ignition coil arrived today. It's from the Bosch Motorsports catalog, designated PS-T. Truth be told, it's a passenger car coil used in Alfa Romeos in the early 2000s. Most importantly: it fi...
