Project Miata Update

One of the main benefits to ITBs is their very small throttled volume (that is the volume between the throttle plate and the back of the intake valves), which bestows them with excellent throttle response. Another benefit is that that they have a very large throttle area, which means they can flow a lot more air, without the negative consequences of a single throttle of similar area. You see, throttles must be sized appropriately for the engine. Like the fairy tale of Goldilocks and The Three Bears, you don’t want a throttle that is too big nor too small. Throttles […]

MS Labs CAN Wideband Module V2.1 PCB Front

Project Miata Update

Well that was quick! My new MS Labs CAN Wideband Module with optional OBD-II port has arrived. UPS 3 Day Select all the way across the country arrived in just 2 days! Big thanks to Trackspeed Engineering for the quick order processing. Some observations: The new hardware enclosure is anodized black instead of silver/clear. The case screws are now T10 Torx instead of Phillips head. There is a second serial connector for the OBD-II harness. The PCB is v2.1. Obviously a completely different design to accommodate the OBD-II. No more jumper wires on the back side of the PCB. Sorry […]

Project Miata Update

Trying to troubleshoot random sync loss errors. In this video you can hear the engine stumble momentarily due to a sync loss error at 1:34 and again at 2:44. Data logs show the sync loss for reason #2 (missing tooth at wrong time). This only seems to happen when the CAN module is plugged in. When unplugged, I don’t get the random sync loss errors. I also ran the high speed Composite Logger and the cam and crank signals patterns appear to be normal during the sync loss events. Disappointingly, Reverant has not responded to my last two email inquiries […]
