You may have seen a recent post where I chatted about Toby Broadfield fitting a few Ark Design products which I’d purchased. Well thanks to my mate Ali at Unit18, I got them all hooked up! (Well, I still need to get a harness for the RST, but other than that, the ARK stuff is all plumbed in and working great).
Ali spliced in to the ECU harness for the MFD, and powered the ABC from the ignition; it took quite a while, but the priority was to do the job properly. With Broadfield’s great fabrication work on the HVAC panel, it was only fair to bring the same level of workmanship to the wiring hidden behind it.
I’ve had sufficient time to test the boost controller, and it’s beautifully simple (in stark contrast to something like an AVCR). There are 2 boost settings to choose from, which can be adjusted by changing the actuator value. The gain can also be changed. It takes a bit of trial and error to find the “sweet spot” where you hit your desired boost level with sufficient potency, but when it’s done it’s done! I used the MFD to monitor boost (using the peak boost function). Handily, the ABC has it’s own peak boost function, and it was matched exactly with the MFD, telling me they were both accurate (essential).
I’m running 0.9bar, which seems to be the accepted boost levels for an SR20 on standard turbo and injectors.
So, very happy with the ABC! Look out for a review on the MFD in the very near future, as well as a review for the RST when it’s all hooked up.
