- Controllers input lag comparison - ResetEra
According to comments the DS4 Bluetooth has a very high polling rate maybe another thing that also helps to reduce input lag compared to other controllers and maybe another reason why DS4 battery drains faster dunno, very interesting to see how low that input lag is Last edited: Mar 13, 2019
- The DB2 Conversion Guide - The Truck Stop
I still get lots of inquiries on how to convert the electronic DS4 pump to a mechanical DB2 pump As some of you know, I wrote a manual some years back detailing the conversion Initially, this was sold as a printed booklet, but lately I have been sending it out as a pdf file I have been
- DS4 Injection Pump Output - The Truck Stop

- Max PSI for a DS4 IP? - The Truck Stop
The DS4's only issue is blowing the shaft seal with too much inlet (lift pump) pressure The newer part number Walbro lift pumps have higher pressure The DB2's reference housing pressure for timing and that is set by the rotatory pump in the nose and it's pressure regulator is also in the nose and referenced to the inlet
- Newer ds4 injection pump - The Truck Stop
If this is truly a larger output DS4 and it does work with the PCM, seems to me that the easier part is dialing in the tuning to properly burn the fuel The bigger challenge is dumping the heat once the fuel burns Aside (and semi-related), Peninsular stated to me that the GM OE DS4 (with marine injectors and the ATT) was capable of reaching the P-400's rating of 250 hp 500 ft-lb under the
