MX5 – Dual Throttle Position Sensor

(First posted on MX5 nutz forum in May 2016) I will only need it if/when I get as far as running injectors directly from the DET3 but I thought I’d see what I could do about providing a proper variable TPS for the DET3 while keeping the OEM 3 state TPS for the OEM ECU. […]

MX5 – DET3 Intake Air Temperature Sensor

(First posted on MX5 nutz forum in May 2016) Made some progress with the DET3.  It’s been a bit slow as I’m just taking one step at a time and trying to always give myself a working state to fall back on if things don’t go well with each progression. When I eventually remove the […]

MX5 – ECUMaster DET3 Wiring

(First posted on MX5 nutz forum in April 2016) Having received my ECU Master DET3 I then had to figure out how to wire the thing in.  Like I said I couldn’t find any mx5 specific info for wiring a DET3 but there are example wiring diagrams in the DET3 manuals and obviously there’s plenty […]

MX5 – Supercharger Fitting Finished

(First posted on MX5 nutz forum in February 2016) Got some of the gold heat tape stuff. I also lowered the exhaust heat shield I’d made ages ago so it can stay fitted with the charger on.  I will probably add to the heat shielding or rethink it entirely if I need to but this […]

MX5 – Intercooler Fitting – Pipework Fabrication

(First posted on MX5 nutz forum in February 2016) I thought the next job of plumbing the intercooler in was going to be fairly quick and easy but it took ages of fitting, removing, trimming, refitting… to get everything to line up. Start with a bit of hose trimming.  I find this is the best […]

MX5 – Intercooler Fitting

(First posted on MX5 nutz forum in February 2016) After placing the intercooler and rad in and measuring up I sorted some spacers for the rad and mounts for the intercooler.   and made a bracket to hold the left hand side of the intercooler where there is an existing threaded mount.   the end […]
