I hope it works out - looks like Rehagen racing is anticipating a lot of demand...they have a seperate Spec Iron section on their website already.
I have a question too...the rules state you can use the M-2353-A ABS module but don't say anything about the HCU....so does that mean you can run the ABS w/o the upgraded HCU? From what I recall the stock HCU is not capable of doing what the racing module wants it to do (rate of cycling, etc).
Link below to Nats forum where I asked the same question, Per responses there the rules are being updated wrt the HCU.
