    I'd run a second sensor if there's concern of signal loss from the main tmap. I'd also pose this question on a maker forum where those guys are more versed in custom electronic solutions.

    With a 12psi spring?... i thought the general rule of thumb is you get a spring rated half of what your boost targets are???

    This isn't true. On a given engine, boost at a specific rpm DOES dictate airflow because the engine's profile is generally static. But if you add something like downpipes into the mix; then you've changed the airflow capabilities of the engine. If you keep the CFMs steady, the engine will make the same amount of power but will make lower boost. If you keep the boost steady, the engine will make more power. This is very evident on cars that do not use turbos. Take a look at the CTSV, which has a roots blower setup. The CFMs coming out of the blower are pretty much static assuming temps are about the same. When you add headers on the car and keep everything else the same; you actually lose boost and only gain a small amount of power. When you install a smaller pulley to maintain the original boost levels, it gains a sigificant amount of power.

    You have to understand that boost is the BYPRODUCT of the engine not being able to 'ingest' the full amount of air being shoved into it; it is NOT the result. An engine that can flow more air will be able to ingest MORE than an engine that flows less; therefore the BYPRODUCT of boost will be lower on the engine that flows more air. The turbo flows X amount of air, the engine can ingest Y amounts of it; then X - Y = Z where Z is the effective boost. This is extremely rudimentary but fundamentally covers what is going on in there. At this point, both engines are making the same amount of power as they are running the same turbo. But when the higher flowing engine starts trying to target the same boost level as the lesser flowing engine, then it is flowing a significantly larger amount of air when hitting the same boost targets. Does this make sense? Boost != power; which is why you can put the same turbo on two different engines and they will have WILDLY different powerbands; it all comes down to airflow.

    Hey all, Sorry for the delay, we were finally able to get you guys some dyno #'s for our stage 2 bucketless setup. This was done on our 135i that is running our Platinum Port Injection kit on Arizona's "E85" (E52). It's running the latest BMS E85 flash that targets 11.9:1. 600whp was no problem, not bad for a single pump that is plug and play, under $400 and you still get to keep your original LPFP for returning to stock or dealer visits:naughty: Thanks for your past & as always support!

    AWSAWS started a thread DIY progressive controller? in N54
    Hi Guys, I run meth injection with a JB4 and the FSB. I want to let the JB4 and FSB decide when meth should flow and when it should not. So that I keep the failsafes. I want to control the 12volt signal that is outputted to the pump. Can I use a MOSFET to do this? So that I can pulse the 12v signal depending on what voltage I read from the N20 3.5bar TMAP sensor? The on/off will be controlled by the JB4/FSB but the signal reaching the pump can be controlled by the mosfet. The duty cycle can be changed based on the TMAP signal. Does anyone even know how to make the JB4/FSB do the pulsing itself? Maybe there is no need for a MOSFET. I have asked this to Terry before. Didn't get told how to do it, but I was told it can be done. It might be a bit of a secret with fuel it trying to sell a port injection kit. (From what I understand, you have to be careful not to leech too much off the TMAP or you might end up lowering the voltage and giving false pressure\temp readings back to the car)

    You can see the MAF reading in logs. We only have a MAP sensor, so I think the MAF reading is calculated based on a lookup table with temperature compensation so that reading may not be accurate when you start changing the restrictions in the pipework.

    Another happy ATM owner here. I never understood why they didn't push their product more on this platform. Their prices were reasonable and the build quality and fit and finish were better than anything else out there IMO. Looking forward to seeing what they have coming down the pipe.

    Jee wiz!! Lol. Might be the highest ive heard thus far. Are you planning to up the boost again?... did you start with those 3 springs?

    Also obviously relevant airflow for power is at inlet manifold, not into turbo. Into turbo will just affect wgdc.

    Which log is airflow? Nearest I can see is MAF. PSI at a given rpm will dictate airflow

    Boost doesn't equal airflow. You need to be focusing on the airflow reading in logs, not the boost value. It's not the easiest thing to get your head around but there's plenty of information on these forums and on the great google.
