I'm adding about a 25 shot to my JRSC'd prelude. Will this affect my hondata map in any way? i'm running 550cc injectors

 

Take it back with the 25 shot and get it tuned while using the Nitrous. Get the A/F perfect while under spray, Then dyno it without using the Nitrous and hope you aren't running too rich. Another option would be to burn two seperate chips one for use while spraying/boosting and one for use just boosting. Otherwise you are going to have to run rich while not spraying.

 

I dont see why not. Good luck!!!!

 

Can you run a wetshot thru a JRSC. If so then hondata won't have too much to do with it. The fuel coming from the fuel jet will keep the mixture stoich.. if you have to run a dry shot, then it still shouldn't make a difference, the injectors will give the extra fuel. The only thing is that with the hondata the ignition may be agressive for the all-motor set-up. So maybe burn two chips, one with advanced timing for all motor, and the other with a more mild ignition map. I know there is a way to have switchable programs on a hondata thru a switch. You have to buy some special socket that has a selectors and connects two chips to one port.

 

I ran mine with spray after making 522hp on hondata. it was real rich no matter how I jetted it. i kept going down down down on fuel and up on n20 and it was running like 9:1 fuel and wpuld touch 10.1 maybe. Then i regapped my plugs all the way down to .020 brought the bottle pressure up to 1100 and it cleaned right up. I made finally 565 and it was clean and pretty flat on the fuel curve.
