Lotus with a K24

Post by K24Lotus »

So I am swapping a K24a2 from an '08 TSX into my Lotus. I am using a throttle body from an RSX, engine harness from an RSX, and a 6spd trans from an '08 Civic Si. I have yet to buy an ECU because I am unsure of which one I should get and still be able to use Kpro to it's full extent.

If it makes any difference, I am running a PTE 5558 turbo... and I'd like to be able to tune in anti-lag.

Any help is much appreciated.

You need a KPro with the 02-04 RSX harness & o2 sensor. You will need to change the transmission case to an 02-04 so that you can use the low frequency speed sensor.

What do you mean by anti-lag? Full throttle shift works well with turbos, but the rally style anti lag which adds fual and retards the ignition washes down the bores and wears out the rings very quickly - not recommended.

Can you give me some more info on the speed sensor? I'll be honest, my knowledge of this swap is very limited. It's not very well documented on the Lotus forums. People have done it quite a bit... but nobody ever cares to do in-depth write ups.

Get a 02-04 clutch case & speed sensor and swap the guts of the 08 transmission.

Should I use an RSX ECU or RSX Type S ECU? What are the differences? Do they both use the same engine harness?

The base RSX ECU does not have the reverse lock out.
