hi guys,

me and my mate installed a lt10s into my rb20 over the weekend, started it up, and with the base tune it seems like its idling weird. kind of pops/knocks. . .

tps is showing 0% load.

also im not 100% sure that the knock sensor is hooked up correctly either. . . can anyone post up the wiring diagram for the tps sensor/switch?

i have read that on first start you have to adjust the tps? and lock in the timing??? any suggestions on how to go about??

Any help is appreciated! cheers

Use hand controller to lock timing - Do not rev the motor!

Use timing light to set engine to correct base timing by adjusting the CAS.

When timing is set correctly, unlock timing with the hand controller.

You have the Microtech manual right?

Also the Microtech doesn't use the knock sensors.

ok, so ive sorted out the tps. microtech is showing 0% then 99% with throttle.

im still not 100% about the CAS wiring. . .

Also, since ive relocated my battery to the boot. when i switch on my isolator switch, sometimes it seems like the coils spark and it even pops! any ideas on what i should check??

Cheers!

check yellow pages and find an auto elec in your area

but it really is, for the time it takes and people trying to diagnose it over the net without realtime testing and by the sounds of it there is some major issues with how ever it has been wired up.

all the diagrams needed are on the microtech website, we get guys ringing 10000 times a week with similar issues and it is always wiring related, so unfortunately we just refer them straight to a dealer of whichever product it is. I dont take on half wired jobs as it often takes longer to fix than a new install...

jump on the microtech website and check you cas wiring to their diagrams

hey trent, its got a base map on it, ive gone through the tps set-up and adjusted the timing to 10btdc, but its still running really rough. is that common?

whats the idle af?

A microleb is a downgrade from the stock ECU, personally I'd sell it. They don't have closed loop O2 feedback so you are going to get rubbish economy unless someone spends hours and hours on the lower load cells when tuning it.

its a dedicated drift car, so i dont care for economy lol

pulled the plugs out trent and there soaked in fuel....thats base mapping for ya.... gonna chuck in the 750's i got and bring it in on the 9th

yeah its showing 14.7 on the h/c. tried trimming it down to 20% but its still rich. . . plugs are soaked in fuel. . .

ignore that, its about 1000000000000000000000 light years off being accurate. use a real lambda sensor or lean it off in steps until it stalls then about 2 page up steps will get it idling if the wiring etc is all correct

Agreed. Just keep trimming it down. Is the vacuum/ boost line connected?

    • Block bump. $400. As above cyl 6 needs bore or sleeve.
    • I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.
    • I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.
    • From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.
    • They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
