Hey, I really Really need some help to get my car running well enough to get it to the tune shop!

My setup is RB20DET, HKS 2530, Power FC, RX7 460cc Red top injectors, Z32 AFM, Walbro 255HP Fuel pump! And the normal stuff, FM Intercooler, 3" Exhaust, HKS pod, HKS BOV!

What injectors % should i be running and air flow %???? Ive tried trimming the map down as it seems to be too rich! but still the idle is up and down and it just isnt right!

Could someone check on their car with a simpair setup! Any help would be much appreciated as my babys been off the road for 6 months now and finnally everythings modified ready to go now!

Thanks

- Luke!

choose z32 80mm afm in the airflow setting menu and leave at 100% air flow......u can pull abit out the injectors..... had my car running on 94% with gtr injectors to get it to the workshop....was running like a hairy goat. Other option is to use ur NRMA road service if you have and arragnge a tow truck......helped me out once or twice.

Let the tuner worry about the idle....thats what your paying him for.

Thanks for your reply, i have changed it to Z32 AFM, also the tuner is 4 hours drive away, so as you can imagine i wanna get the AF ratio as close as i can, so i dont foul up or melt plugs on the drive there, it wouldnt be fun changing the plugs on the side of the road...:rofl:

The PFC will be in closed loop at normal temperature idle, so if the idle speed is jumping around it's not the tune. Usual problem is vacuum leak. So triple check all of the hoses.

Getting a modified car to idle is sometimes harder than getting power out of it. After you have checked all of the connections I strongly suggest you forget about tuning the idle and move on . The PFC will also run closed loop for cruise, so it will get the A/F ratios OK for that. Check how it runs on light throttle, it may take a few minutes to learn. Thne a 4 hour drive should be a doddle, just don't do it in peak hour (leave home at 2 am) and don't get out of cruise mode (resist the temptation).

Hope that helps:cheers:

Thanks HEaps mate!!!!!!! ill give that a go, i was going to leave real early one morning! and take a mate and a set of spark plugs with me and of course the appropriate tools for the job!

Thanks RB power, ill try them at 65%

same set up except for Q45 AFM ... i run mine at 50%  

200Kw here they come !!  

good luck :D

Hey, Does that mean you have 460cc Rx7 injectors?

If so is there any chance you could check out what the injector % is set to? and the pulse rate of the injectors...thanks!

As far as i know S5 RX7 injectors are actually 550cc ... not 100% sure tho

and they are set at 50% duty.. now the column next to it is set at 0.00ms through all 6.

hope that helps

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
