I just finished my turbo install with a smc+ and 450s for management. When I hold my rev at about 4g it cuts out and drops down to 3.5 and goes back then drops again. Is this from it running lean, rich or a whole nother problem. I want to solve this before I drive it cause it's freaking me out. My SMC settings are
idle-40%
1-2k-38%
2-3k-37%
3-4k-36%
4-5k-35%
5-6k-34%
6-7K-33%
7-8k-32%

 

Someone must know what is happening. I want to get this car finished and enjoy the boost. Any help would be greatly appreciated.

 

try moving your numbers up or down a few per rpm and see if it gets worse or better, go down across the board, check it. if not go up..it may be lean or rich right at that rpm point..youll have to adjust to see, take it out and drive it to and see what happens, its a differant story under load, just lay off boosting if it cuts and check the A/f

 

Could be the fuel cut out on you stock ecu from your map sensor reading too much voltage(manifold absolutepressure) Do you have a Fuel cut eliminator or zener diode to bleed off voltage?? The missing link does not always bleed enough pressure off to stop the map sensor from reading boost. could also be detonation - just some thoughts - I am not sure if this applies to Honda's or not .
