Rb25det Dyno Tune Went Wired. Can Any One Tell Me What Might Be Causing It.

[hypergear]

slightly off topic but stao when i get my nissan bolt flange for my atr28g3 will that be the same as a atr43g3?!?

Technically yes.

Also compression test and it came up

120 145 120 125 125 130

Is this a average result for a Rb25det engine?

according to the nissan workshop manual the limit value is 9.2 kg/cm2 or roughly 135psi

Looks like it is missing very badly. Does it just drop in power dramatically? or does it pop and fart around at those dips in the power graph ? I would be checking the earths, sparkplugs, ignitor module, coil packs if it is missing.

If it is jsut dropping in power check the fuel pump, is the computer retarding the ignition something shocking for some reason, how is it being tuned? Intercooler pipes sucking shut, boost leak?

Does it run really rich when these dips happen, weird noises? need more information dude.
