K-Swap Tune Analysis

Post by Omni »

Good afternoon everyone, I have a K24A2 swapped MR2 that I bought with the swap already completed. The previous owner said that it has been dyno tuned for E85, but I am not finding an Ethanol content sensor installed. Also, the tune does not have an Ethanol sensor enabled in KManager; the Ethanol content input is disabled. The car runs pretty well with its current tune, but I think it could be better.

I have a few questions for you Honda gurus.

1. Could you review the attached .kal file and tell me if it looks like the car has been tuned with E85?
2. From the .kal file, could you tell if I may be able to just run 93 on this tune? I would like to use 93 instead of E85 because it's a hassle to get to one of the few E85 stations around my area.
3. If I cannot run 93 on the current tune, then could you help point me to a tune that would work for running my car on 93? I do not really have interest in dyno tuning the car because it's solely a street car. A street tune would be ideal, and I am thinking to try the auto tune feature in KManager.

Let me know if you guys need more info, and thank you in advance.

If it is tuned for E85 you will not be able to put in pump gas as it will have to be retuned for that. If you plan to use varying percentages of ethanol you should get a Flex fuel sensor installed and set up properly to adjust things a necessary without having to switch between calibrations.

Alright, I understand. Thank you, Spunkster! I was just wondering if one is able to tell if the current map has indicators that it is tuned to E85. I will research some more, and I think I'll eventually get it re-tuned to pump gas.
