k24a2 from 07 tsx in 1991 mr2

Post by tumblingtwerp9 » Tue Mar 14, 2017 11:20 am

I am looking at swapping a k24a2 from an 07 tsx into my 1991 mr2. I will be using the mr2 transmission which is cable driven for the speedo. I plan to turbo the motor and shoot for about 600whp on e85. Will a flashpro be able to handle this job or would I be better off with a full standalone or is there a way to put a kpro in this setup.

For this you would be better off with a K-Pro and you will have to convert it to a regular cable throttle body. You may have issues with the speed sensor as the ECU will need a proper speed signal for it to operate properly.

Would it be possible to pick up speed signal off an abs sensor? What kind of issues would I have with no speed signal?

What type of signal is the ABS?

Without a speed signal, you will have issues with VTEC, Boost by gear and any gear based compensations.

You would be much better using the KPro rather than the FlashPro as otherwise the 07 ECU would want to see all the vehicles systems (VSA,ABS,TCS,dash,TPMS etc).
Also with the KPro you can input an arbitrary frequency speed signal as the speed input, but you would need to find a converter from the ABS to a 0-5V waveform. ABS sensors can be inductive or hall effect current based, and it is imperative that you don't connect an inductive output to anything not designed to handle the high voltage generated at speed.
