I hugely appreciate that. Thankyou. Where I had scaled up the table for increased Map, I felt concerned I was then reducing those numbers to be on target for my AFR. Thankyou. On a similiar note. Would the numbers ever decline, would you actually notice running into high back pressure, or is that never reflected in the fuel map? I had assumed, that the fuel map would generally be a result and a picture of your torque curve at least Thankyou again for your help

Thankyou. I am in traditional mode. Do you want me to log a low boost then high boost for example?

Hello all, Ive noticed when approaching 20psi mark, that whilst the AFR remain good, im not actually requesting higher figures in my fuel table. IAT are in a good place, normally increases by around 10c after the pull in the current weather, finishing at 30c. ambient is around 10c. Is this a case of running out of efficiency, or possibly high back pressure? There is a rising rate fuel reg, and pressure is increasing accordingly with MAP. Differential fuel pressure at the start of the run is 310kPa to 290kPa Any help appreciated,

Hi guys. Thanks for all your replies. It's sorted now. I must have always had a small leak o. The diaphragm. But since last doing a bolt check and refitting the top of the gate there is now no leak, and the way I had it plumbed, air pressure would stay trapped in the top of the gate. I've since redone the plumbing to a more conventional style and it's working well,

Bit of an odd one. Since trying to sort closed loop boost control, I've run into a new issue which I believe is with my turbosmart gen 4. I have a Mac 3 port plumbed to top and bottom. This has worked well for this season. Now, no duty cycle and I'll make 8psi throughout the whole range. As little as 15 percent duty and it'll make 15psi. A couple percent makes a massive difference. I believe what's happening. Maybe. Is that when the stage 1 is active. It's pressurising the top of the wastegate. This is then sealed shut and doesn't bleed off it's air due to it being plumbed in to the Mac valve port. My question is.. should the wastegate actually bleed off some of it's pressure over a second or so? You can apply pressure to it on a test bench and it holds it's air. I believe this is why I'm having boost issues. Is this true or am I barking up the wrong tree. Clutch at straws a bit . I've tested the Mac valve, and the ports/diaphragm on the valve work ok on a bench.

Yes it was just as a display but does appear to be a rather clunky way of going about something I had hoped was simple!

Understood from both counts. Thought it would work! It's a tablet with only one usb charging and transfer port so was clutching at straws. It did briefly work but with engine off. It was broadcasting to a virtual com port on the tablet

Ah, it is a G4X?

Having trouble with this! Keep having the following error 1015 I have tried playing with connection speeds! Any advice?
