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...

With the vacuum manifold and vacuum port problem solved, I've moved on to how the actuator will work. I found a sweet 8mm ID CNC router coupler that allows the actuator to directly drive the throttle ...

Last night's project was the vacuum manifold. Each of the just created throttle body vacuum ports will be connected to the manifold. There are two additional ports: one goes to the MAP sensor (the who...

Wow that is a great job... Interesting what you were saying about your car having double sensors for everything. Our earlier SR3 00376 was set up the same way and also running the Life Racing F88 ECU...

One of the first sub-tasks is to modify the throttle bodies to support a MAP (manifold absolute pressure, aka vacuum) sensor. There are no provisions for a vacuum port anywhere on them. Jenvey (the OE...

Wow, that is a big job! I am looking forward to following your progress! Charley

I'm upgrading my SR8 to a MoTeC M150 GPRP (general purpose racing paddle shift) controller. I found that the gearbox controller (by Geartronics) was so old that the tuning software didn't work, and th...

Hi Philipe, A wet sump engine will in general run hotter than a dry sump due to the oil being stored within the engine - with the dry sump tank there is some cooling just from having the oil out of th...

Thank you so much Dan for the valuable advice! I will definitely be checking the cooler and grub screw tomorrow!

this is something i'll be attempting to do myself for the very first time next weekend. It looks like it will be worth getting the engine load leveller as @ntf3000 suggests. I'm quite scared but been...

A slide hammer is not needed to pull the engine. A long screwdriver or brass drift, and sometimes lifting the engine slightly to remove stress on the engine cradle pins works well. A gentle push or ...

So far no, but I haven't had the car on the ground yet. There is an audible click in both directions so I have hope.
