    Need help with spray

    As some of my friends know, my car will be going through some mods these next few weeks. One of the main mods is nitrous. I was looking at the drive by wire spray kit from holley NOS. my question to you guys is who can do a good job for the install and the somewhat tune? This will be going on a lexus IS-F, so of course, like the toyota supra, ecm is fkn uncrackable. And there is no tuning for this car. The ecm will learn through hard driving and seat time what mods have been done. Ive been looking around in the f forums and most guys run @ 100-150 shot wet. This is where i want to be, just dont know who to trust around here. Had some shop tell me get another ecm and we can tune it no problem. I immediately hung up and kept searching, another shop told me its a easy car to tune. Again hung up and left it alone. Just trying to get some advice as to where i can take the car to get the juice installed and done right.

    Feedback will be appreciated.

    It's all in how you set the system up. Give the shop a buzz and we can talk you through the details as far as whats possible.

    Well with wet N20 you can kind of tune it yourself. Install a wide band and watch the a/f ratio. If she goes a little lean put in a larger fuel jet. It's that simple. Check online for tips on where to start for jet sizes for the desired Hp. You might want to retard the timing some if it advances a lot from the factory. I'm not sure how you would be able to do that though. Otherwise add a fuel pressure safety switch, a rpm window switch, a wot switch and a bottle heater.

    Have fun nitrous rocks!!

    There is a system out there that will work on your car for tuning. I did a lot of research on the IS-F when I used to work at SSA, we had one that we were doing a full stand alone on with a fully built sleeved motor and a twin turbo setup. Unfortunately the owner ran out of funds and the project ended prematurely but I can help you get it sorted out if you like. Just PM me.. The car uses staged injection and can be tuned if your smart enough to know how to set it up ; )
