rb20 strangness

[rbforsale]

my rb is doing something really oddwhen i accelerate wot ,between 3500 and 5500 it falls flat on its facegood spark,iridiums,gapped right.brandnew coil packs,good maf signalgood tps signal,no boost leaks,good fuel preasure,cas goodsafc set to initialize signal set to 1in 1 out....some one said its sposed to be2 in 4 out,but it was even worse so set back to normalany one have any idea's...

how long have you had the safc on the car? did the car do this before/after the safc? can you remove the safc and make sure that's not part of the problem? what happens after 5500? do you have a stock maf? Anytime you have a vague problem like this the more info the better.

yay timing and knock retard.ecu is pulling timing and is in the knock map because you have other issues.im gonna guess you have your car 'tuned' with the safc...

whenn the issue happens its as if its only firing 3 cylinders speraticlyas if it where dumping boost,also when i was on the highway at one pointthe waste gate actuater came off and the car never did the"problem"just didnt have boost,so i disconected my boost controllerand put back to normal,yet it still does it but only at 6500 for like a split second,so i thought it might be the boost controller,replaced with brand new one and still did it,only running 12 psi...and no i didnt "tune anything" with the safc,i didnt start having this problem until i pulled out the silencer in my muffler?!?!?.....random: myabe its running lean>but the safc hasnt even been messed with,all voltage through the afc is registering corectlypossibly the 02 sencer?it looks fine...?

the o2 sensor has no input under WOT driving. only partial throttle cruise.

whats your timing set at? rb's are hyper sensitive to timing.

cas is set to factory setting never been moved,brand new timing belt from greddy and was at perfect tdc when complete.by the way,how DO you 'retard' timing on the rb's? probly a dumb question sence i know it has to do with the cas,at least i think so?

[Joe]

i meant ignition timing, not cam timing.

search on how to set your timing, its been covered many times.
