just installed a innovate wide band afr gge and lc1
on idle afr is 11.8 when on idle enrichment and settles to 12.0 when warm and on idle..car has 550 primary/1600 secondaries and is street ported..just wondering whether this could be leaned out a bit on idle as seems a bit rich.using apexi can u lean out the idle and cruise cells without leaning out the on boost area..(i wont be doing it i hasten to add just in case someone thinks i know what i am talking about)..i thought idle afr shd be around the 14.0 area or s this just for a piston car

Nice call Carl

Yes you can lean it out to idle at 14.0 without affecting the other cells, using the apexi.

I think you will find around 12 is the best for a smooth idle. If you aim for 14 idle will suffer.

I have uploaded the Mazda target mixture map (taken from the Datalogit site) and you will see there is only a small cruise area that the have 1\'s which is Theoretical 14.7

interesting how did the rx7 ever pass emmissions as i only have standard 550 in my primaries which give co reading of approx 6.0% that leaves an awful lot of work for a cat to clean up which is why i thought standard rx7 must have a leaner idle

Two words... Air and Pump

I get a basic idle of 12:1 afr on 850cc primaries. It would seem that you can remove some fuel from the cruise areas of the fuel map. But i  have found this to make the car harder to drive and a bit jerky for my liking.

Why do people keep coming out with this non member predujice on this forum when at least 70% of all posts  that are here to help each other came from the (non members) in the first place. Including me!  :flamed

Well I guess that it has something to do with the fact that this is a club.
It is based on people paying to be members.
It is not a prejudice,just seems that there are alot of freeloaders on here.
This will be tidied up very soon,so there will no longer be a problem anyway.
The amount it cost\'s to be a member has got to be worth it just for all of the money people save on advice.
It is a pity that the non members do not appreciate one simple fact,this club and forum is not free,it is paid for by the paying membersSo why should all of those paying sell themselves out with good info to those not paying?

but all the other forums are open and free this is the only one where membership seems to be an issue.now i agree the 25.00 is not a lot of money but if i had to join every forum i wld be paying about 300.00 a year.i dont consider myself a freeloader as if i can offer any help or advice over something that has happened to me then i do.thats what i thought the forum was for..i can only assume this is going to become a members only club soon by what carl has said.i hope it doesnt destroy itself in the process.i have never seen this become an issue on other forums..just tallied up and i am a poster on 12 other forums from fords to subarus/toyota/v8s but i drive a rotary and if there was some info i could pass on to a ford/subaru owner ect thru the forum then i would be happy to do so

Why didn\'t this happen from day 1 then? Would of saved a lot of bitching, wouldn\'t it.

Basically though the paying members get discounts for entry to events and vendor/insurance discounts etc and non members don\'t. Kind of evens up in the end though doesn\'t it?  :wave

Many other clubs have this policy.
Someone like you Royston and you RX7 veilside would obviously be an asset to the club,so why not join?
