btw gimme *useful post* thingo so that i can go into the trading forum (cant get in for some reason)
sorry to be blunt dude but your comment was far from useful. This has to be the most primitive way of checking that your vac line is actually working. And yes i do have an aftermarket ECU, and it doesn't make a difference really. AFM - lols its a B series honda motor dude.

Also like i said in my previous posts ive explained that ive tried different vac lines and sizes to test so clamping, or blocked lines are not the case.
