If it was running to lean on idle it would stumble and stall, infact you want it as lean as possible without any hesitation on throttle.
What are you using to measure AFR?
With a PFC and commander you can look at TPS and MAP sensor, infact all the sensor voltages.
Getting a PFC would save you a lot of time checking sensors.

cool looks like I will be getting one then? AFR gauge to measure but it is one of those lean/optimal/rich ones??? came with the car.... It is running lovely at idle about 850rpm it is just the reving/driving of the car it does like rev been thrown at it so to speak, only likes progressional revs at idle and nothing above 4000 rpm when trying to drive it??? needs mapping though

She sounds rich to me mate,
You want a innovate or aem with a number read out really as the swing type guages are a bit hard to trace,
Also depends if the emanage has fuel cut/boost cut and which will also give you problems,
The standard ecu is designed to run twins so if you piggyback with most of the old solonoids missing it may go into limp mode too
 
standalone is the only way

[123tom123tom]

ok cheers matey, p.s ant forgot about ecu either was going to try it on the car but not going to bother now just going to get the apexi

[a.tapos]

ok mate thats great thanks

daves got a 95 on but didnt know what age your is.

[123tom123tom]

mine is a 1993. going to upload vids in a bit the runs like a bag of you know what, dont know if it is coils, leads,
god knows

[123tom123tom]

Right here are two vids for you look at, see what you think and all oppinions and theories are welcome.....
 
As you can see in the interior vid, it is like the car is hesitating and looks especially around the 4k mark???
 
Also if you look at the oil pressure it goes quite high, dont know if this is right or not?
 
the car should rev without issues shouldnt it even without a map as there is no boost present?? coil breakdown :2eek i just dont no
 

[a.tapos]

well its not going lean at the 4k mark so wouldnt suspect fuelling id say possibly make sure the double throtttle is open/vac hoses etc,like i say though if youve disconnected all the other solonoids and wastegate controls it may just be the standard ecu cutting the spark to prevent damage as it knows it cant control whatever its seeing.
 
Does look like a very obvious limiting/cut going on.

[123tom123tom]

 
 
this is the external view?
 
Again as you can see very obvious limiting and popping???
 
A guy on the forum said he had the exact same problem and it was ecu that had got damp and terminals on ecu needed cleaning???
 
Now this made me think as my carpet underneath is wet near the ecu???

[123tom123tom]

 

 
I found this today? wet floor and a adapted harness to my standard ecu but nothing on it just cut wires??? thinking there may be some shorting or rusting of terminals :censored:

I work in the Food industry as an Electrical Maintenance Engineer and we commonly get operators washing down panels etc and causing havoc to electrical systems. We use electrical contact cleaner that drives out moisture and cleans salts etc from contacts.
1 really good product is ROCOL electra clean distributed by BSL Brammer and this is a huge bearing supplier with a depo in most citys. I swear by this stuff. I would take all edge connectors off and liberally spray on contacts. I would disconnect battery as well and allow 10 mins to evaporate, then do an ecu reset ( positive off brake and clutch down for 10 secs.....cant remember precise procedure at mo). Another supplier would be RS components, Farnells or Tandy type place. You dont want the contact lube as that just makes a mess a bit like WD40, and allow to air dry warm up as has a freezing action like most aerosols so makes plastic brittle.  Can should be about a £10.00 worth a try....

[123tom123tom]

Ok i have cleaned all connections today and it is still the same?? as soon as i stamp on the accelerator  it hesitates and dies back in the revs.... it is overfueling like mad really really bad and there is a definate like stop bit like a lowered rev limiter at 4000-4500 rpm?
 
some thing is wrong but I dont think it is serious as the car will rev past that point if done progressively although again it will start to break down again at about 6500-7000 rpm
 
could this be coilpack related, ht leads breaking down, I am running out of ideas
 
what ever it is, is causing it to serious over fuel when running, I revved the car up to about 5000 rpm and on the droop in revs the exhaust set on fire inside, not popping flames actually on fire for about 5 seconds

Just sounds like its over fueling. Could be struggling to fire the spark (possibly).

Did you buy the PFC ? If you did wait till it comes then get it bunged in and off to a tuner.

do you know any tuner not far from me Barnsley, south yorkshire

Its hesitating at around when the secondary injectors start to come in, are all the injectors ok/mapped in correctly?
