As you may of seen from my Instagram a while ago I installed a Haltech 1500 Elite. π₯π₯π₯π₯
Why may you ask as the OEM ECU is perfectly capable of being tuned with the likes of ECUTEK? π‘
Well.. apart from the main standalone features, live tuning, flex-fuel, traction control, CAN BUS wideband etc etc.. I’m very much about having one location where everything can feed into, what I mean by this is having the ability to feed in oil pressure, oil temperature, fuel pressure, boost control.
The reason for this is you can have some pretty good fail safes / warnings in place to prevent damage when things start to go south plus as I’m using a Plex uSDM-102 I can feed all of this information directly to the Dash via CAN Bus, I was all about having loads of gauges but in reality on track you really are not going to notice something wrong before the damage has been done.
Old Setup Oil Temperature / OBDII Gauge / Oil Pressure 
New Setup more in eye line of sight 
Plex uSDM-102
At least with having it all into the ECU you can for example have a RPM limit in place & the dash flash if your having low oil pressure or the AFR have got lean, not that I expect to have any issues but it’s handy.
One of the biggest thing is the ability to data log, now the uSDM-102 has this & was the main reason I went for it when I had the OEM ECU, the ability to log on the fly without having the laptop running and plugged.
Very handy when funny things start to happen, you have half a chance to figure it out. π
(If anyone wants to run the Plex uSDM-102 with the OEM ECU I have the config file for it to utilise CAN Bus as the normal OBDII applications are quite slow, this includes pretty much everything the ECU outputs that would be needed)

The joys of the Haltech is they support the NC setup & CAN Bus setup so apart from a little wiring it will work out of the box.
The wiring side of things was fun π I big big shout out to James Hyatt for creating the original document regarding OEM pinouts > Haltech.
I’ve since updated the file to includes the colour coded wires to really help with anyone doing a future install.

As you are unable to purchase or get hold of the OEM ECU connectors you are forced into using the OEM units which you open up and remove the control board from the connector itself, this is to allow a PnP feature without having to do a new wiring loam for the engine bay, in hindsight it may of just been easier to do that?!
I had a good friend Ian Mockett come over and give me hand, luckily he builds Motorsport wiring for a living so at least someone knew what they were doing. π
To protect the wires we opted for plugging them, what that means is filling all the gaps with silicone this will help prevent any water getting in and causing problems due to the plug being in the engine bay.
I’m afraid I didn’t take many photos during the process as I was the main man calling out which pin goes to which colour wire, I’ve got a few more sensors to wire in before it’s 100% completed but here are a few I did take during the process.. looks scary I know…. π€¦ββοΈ
Overall it wasn’t a bad job and I’d 100% do it again. β
I’ll update you with the finished product once it’s all done, but so far with testing it’s all working! β
