Lol, Yeah or put one of these on there then go straight out & enjoy your boat!are you data logging all of the running its doing? even if it doesn't plane, data log that so you can go back and make changes to the tune in the areas where the issues are occurring. Post up your data logs, this could be a good little thread with some real life info on tuning efi. Have you ensured all your constants are set correctly? have you verified the timing on a timing light with what the PCM is saying it is? Start with the basics, verify timing, verify all your constants are correct, now that you have it starting and idling properly, will it free rev? can you rev it or does it stumble real bad? if so, that needs to be changed before you should try actually accelerating. Also, make your timing a constant value and not a full customized table. have idle be low, in the 10-12 range and everything above idle should be 23-25 degrees, just block the whole thing out (kinda like a locked dist would do) this will give you a safe constant setting so you can focus on the fuel table. you should be in 100% open loop and slowly beginning to modify the VE table based on your data logs and how the engine is responding in relation to what you are seeing on the wideband. don't immediately jump to trying to drive the boat or WOT. go slow, as soon as it stumbles back out of it, shut it off and check your datalog to make the necessary changes, then retry. Tuning EFI is a time intensive process, especially if its your first time, and you want to ensure your first time tuning doesn't end in disaster. Be patient! One change at a time, and datalog EVERYTHING.
