Adaptronic Plug-in Select ECU - MX5 NB8BConnecting the plug-in select ECU is amazingly simple, I ran the supplied hose from the intake manifold to the map port on the Adaptronic Select, unplugged the factory ECU (3 plugs) and plugged them into the Adaptronic, put the keys in the ignition and it started no dramas.
The ECU comes with a USB cable and I downloaded the latest version of Adaptronic's WARI software. A little stuffing about to get the driver to load on Windows8 and I was good to go.
I wanted to do the mods in steps so I could narrow down any issue. When I installed Dann's exhaust I had screwed in the wideband O2 sensor and run the wires for the
Innovate Motorsports LC-2.
It was great that Kenson had recently installed his adaptronic, he was great for reassuring me I was on the right track.
The LC-2 comes with a digital output plug (similar to a headphone jack) that simply plugs into the front of the Adaptronic. The LC-2 isn't listed in the Adaptronic Software yet as it replaces the LC-1, the LC-1 setting works. Turned the key again and it started.
The next step was to install my BEGI intake and no longer use the AFM. Installed it, started the car and once again it sprang to life. It's great when things just work.
Next I installed the
Injector Dynamics ID725s, I'd read about them on the Adaptronic forum and I know Tim Kent was happy with his. I ordered them with plug and play adaptors. It's a bit of a pain to get the top of the intake manifold off and access the injectors. Strut brace comes off, then I removed the throttle body and the top of the intake. From past experiences I was very cautious removing the stock injectors. I covered the open side of the intake manifold so nothing could fall in then loosened the fuel rail bolts. There are plastic spacers on the fuel rail and I took a lot of care not to drop them into the engine. To have enough slack to manipulate the fuel rail I unbolted the plugs from the back of the head. The ID725s look longer than the stock injectors but they slipped in fine. I put it all back together and opened WARI to change the ecu settings for the new injectors. Based on what I thought would work and it wouldn't idle. [url="http://mx5cartalk.com/forum/viewtopic.php?p=786158#p786158"]See my comments here[/url]. Kenson had drummed home to me about DEADTIMES, DEADTIMES, DEADTIMES, I know Saboteur had done a stack of testing, his car has fuel regulator set to 3 bar and the SE pressure fluctuates. As pressure increases so does the deadtime, I started with Tim's deadtimes and added 10 to each, the car started and idled. I added another 10 to each and it ran even better. Things were back on track.
Last Sunday Kenny came over and checked my settings, showed me where i'd make a couple of stupid mistakes and helped me put in a basic (no boost) tune with Adaptronics own self learning mode.
