Turbo Speed Input: G4+ Thunder DI 11-16

Recommended Posts

I have a limited understanding in IC's and am not really sure what to make of the diagrams on the first page. I understand that this IC is used to reduce the frequency to something under the 500hz limit that the non-thunder ECU's can handle however the wiring side is what i need help with.

I understand that pin Q5 is the ÷10 output that gets fed into the ECU's DI input.

+5VDC from ECU sensor power supply goes to which pin on the IC?
Turbo speed sensor original output goes to what pin on the IC?
Does the IC need power earth or sensor earth fed into it and on what pin?


Thanks for you help mate, much appreciated.

> +5VDC from ECU sensor power supply goes to which pin on the IC? VDD - pin 16
> Turbo speed sensor original output goes to what pin on the IC? D = Data - pin 1
> Does the IC need power earth or sensor earth fed into it and on what pin? I'd ground to chassis, all the ones shown (Jam 1-5 and R for reset) and VSS

Awesome mate thanks for the info.

I am running the 6758 which is the only 12 blade turbo in the EFR range so i could also use the divide by 8 function to get a better resolution.

150,000 (max RPM) * 12 = 1,800,000
1,800,000 / 60 = 30,000 Hz
30,000 / 8 = 3,750 Hz
3,750 / 8 = 468.75 Hz

Which is under the 'roundabout' limit of 500hz that the fury/extreme can handle.
