live data

Hi guys done some live data question is manifold pressure 98.27kpa
should this figure rise when revs increased or stay the same through rev range.
luanch x431 diag report
coolant temp 78.0 dec
inlet air 24.9 dec
feul rail 47.1 dec
manifold pressure 98.27 kpa
ambient pressure 101.32 kpa
air flow 61.70 kg/hr
engine speed 744.0 rpm
how does the rest of these figure look
cheers

Mike. At work at the mo but will hook up my Hawkeye tomorrow and post my figures for the list you have given. Should be done about 11ish. Cheers Andy

cheers m8

Hi Mike here are the readings of mine compared to yours.


Coolant Temp 77.0
Inlet Air 41.3
Fuel Temp 66.7
Manifold pressure 102.6
Manifold pressure raw 102.2
Ambient pressure 100.2
Ambient pressure raw 99.9
Air flow 48.2
RPM 760

Hope this helps mate. If you need any more readings just let me know. Cheers Andy

ps sorry for the delay had to take the good lady out shopping.

no probs cheers doesn't look to different from mine
was having stutters around 1500 revs so made a new egr blanking plate and fiited it to the exhuast manifold seems to have fixed problem .
thanks again mike

Air flow is slightly high, but not bad - Should be 55 to 60 at idle with all loads off the vehicle (A/C, lights etc). Worth taking a snapshot at 2,000 rpm - should be around 190 to 200.

Everything else ok.

Manifold pressure will only change when driving the vehicle, not sat still revving the engine. The engine needs to be under load. Should be getting 200 to 225kPa there if everything OK.

Good luck.

thanks wslr air flow goes up over 400 when reved up to 3000 rpm or so
