Injector Settings?

[Jimjitsu]

car was running great intill i fitted the new rail ,secondarys and fpr the fpr is a aeromotive one the whole fuel kit was bought from rx7 store this one here ----> http://www.rx7store.net/product_p/extremefuelfd.htm ill try turning the base pressure down see if that sorts it thanks for the help and advise so far guys :cheers

ok did a bit of digging for ya to double check, stock base pressure is 37psi at 0 psi of boost, so disconnect the vacuum tube to the fpr and set to 37psi then reconnect, so on idle you are pulling vacuum so you will see fuel pressure drop below 37psi

thanks for checking around for me blitz I went and had another look at it. Before I did anything I turned the adjustment screw down on the fpr pulled the vac pipe and tried starting it again much to my surprise the fuel pressure shot up to 70 psi :/ quickley turned that bugger down to around the 37 mark put the vac pipe back on and it sounded alot better with much less smoke allthough its not going brrrap brrap anymore it still only sounds like its firing on one rotor and still a tiny bit of smoke is it possible something got damaged in the brief time it was running with high pressure it has not been driven at all just started and left running for no longer than a minute i would say

you wont have damaged anything, glad it sounds better though as it was defo overfueling on 70 psi bar pressure lol, the reason it probably sounds a bit lumpy you might have flooded one of the rotors or fouled up one of the plugs from running rich, I would let it run for a bout 15 minutes and it will clear itself blip the throttle a few times or go for a drive keeping under 4k rpm.

thanks blitz gonna take it round the block to see if it clears as my neighbours are starting to freak at the noise of me starting it then turning it off thought 70 psi might be a tad high lol

[Jimjitsu]

well had it running for about 20 minutes doesnt seem to want to clear you should have seen the looks i was getting off people walking past lol (i live on a high street) pop,pop,pop,pop,brr,brrrr,brrbr,BANG,pop,pop,pop smoke coming out the back was trying not to laugh from the evil stares i was getting maybe i should just buy some new plugs hehe

dude where are my dues dont think your taking all the credit...

infact any of it!!!    :spank

[Jimjitsu]

didnt see you under the bonnet finding it so bog off:p

[karl_tate]

glad its sorted, was going to suggest MAP sensor as it will smoke like hell and sound like its on one rotar with that unconnected.

[BlitzBoy]

lol you had the map sensor vacuum pipe disconnected ?? haha glad it was a easy fix, now drive it carefully to Pips

[Jimjitsu]

yeah I gave myself some of these :Hammer :Hammer :Hammer first things first make sure you put it back together right todays "im a doughnut award" goes to me :Giggle
