Everyone has been so patient while we have been in development over the past year and half with this kit. Finally we are ready to officially release the system for sale to the public.
We are offering promotional pricing for a limited time on the system. Please feel free to contact us directly with any questions and we will do our best to answer them. Radium Engineering - Blog - New Product: PnP EMS for Lotus 2ZZ-GE
Do I have to purchase the $300 Aux Harness if I want to use a Wideband O2 sensor ? Or there is a way to splice into the actual harness...
I have no use of the relay, speed density and boost controller as I already have a eboost2 controller.
Great question. The aux harness is not necessary if you are just connecting a wideband. The output from your wideband gauge (or controller) will simply splice to the 12pin Deutsch connector (Pin4) on the main harness side.
ECU looks great... but some of the extras seem a bit unreasonable. Advertised as a simple PNP solution yet "NOTE: For a trouble-free plug n' play connection, the Radium Auxiliary Harness should also be purchased"[$299 extra]. And 99$ for a switch?
For a trouble-free plug n' play connection, the Radium Auxiliary Harness should also be purchased
The EMS kit comes standard with a "main" harness. The "auxiliary" harness is only used for ancillary options (speed density, wideband 02 hookup, boost control, and prewired fuse/relay output). However, ALL of these auxiliary components can be wired up manually by the user instead of purchasing the aux harness.
Sorry, I am not familar with tuning so this is a bit over my head, but interested in learning. I would imagine you would need something close so the engine doesnt go pop.
Or am I way off base with what this does?
Did you read the website? They will have base tunes for all 3
"Base maps are included for naturally aspirated, supercharged and turbocharged applications. However, not all cars are the same. These tunes need to be verified by a certified AEM tuner before racing. The fuel tuning can be mapped traditionally in 3D, alpha-N, boost compensated, etc. All Radium base calibrations are tuned using 3D alpha-N with 2D boost compensation. Maps can also be password protected by the tuner to prevent unauthorized usage and sharing."
The Radium EMS PnP kit also includes a preconfigured Lotus-specific "workspace". These tabs simplify the tuning process by hiding unnecessary universal graphs, tables, and options that are either permanently setup or not applicable to the 2ZZ-GE. Furthermore, this allows commonly used features such as VVTi, boost control, knock control, traction control, etc. to be easily accessible and not buried in the software.
