I am thinking of having my ECU reprogrammed on my 500EFI. I would like to have it leaned out on the bottom end and bump the REV limiter up a bit. I have a 99 Checkmate ZT 280, I am spinning a worked non lab 24 bravo 1 at 5250 rpm at any air temp. Depending on conditions I am running 69-71 GPS. What are the gains I can expect from it besides eliminating the transom soot? Who does everyone recommend to do this? How much does it cost?

To be honest I would really like to pick up a couple mph on top so I run 70 consitently all day long. I would like to be able to run a 26 lab B1 at the same rpm. Maybe I am asking too much but I though I would ask.

Thanks,

MM

We can program your ECU also. The correct way to do it is weld a 0/2 bung in your exhaust and I will ride in the boat and dial it in. Ohther wise I can put a known cal we do and you could try that first. Tyler

Tyler,

It was great talking to you today. You will be hearing from me in the spring to get this ECU sorted out.

Thanks for your time,

Where can you weld an o/2 bung in a set of CMI'S.Does it have to be close to the exhaust port,or can it be in the tail pipe? Might be able to put it in the tail pipe fairly easily?

Mr Gadgets

Tail pipe is a good spot.. between 9 and 3 o'clock is best. CMI welded mine in the collector at 6 oclock.. the worst spot. But I have been able to run on the same WB O2 all summer. My exhaust is dry all the way to the back, that maybe why I had such good luck with it. Innovate LC-1.

Hope this helps
