What do you think of these readings?

[Wav]

The stealth has a knock reading upto 120 just by free revving, I\'ve changed the timing, plugs, leads and it stills knocks exactly the same :rolleyes: I think i\'ll have to order a second hand knock sensor from tim and try that, the car runs sweet and the afr\'s on boost are below 11 all through the rev range. If a new sensor doesn\'t sort it I think i\'ll just disconnect it:)

Green light?

I was talking about your \'red\' heat light on your dash not the Apexi commander itself (think thats what your talking about).

Thanks for the input chris.  Yes your right, I ment the commander! Im a silly ass! While I was driving the heat light was off.

The heat light always comes on when I turn the car off and leave the ignition â€" Is that what they mean by its telling me there IS a fault?

Higher Octane fuel should help keep knock away. what mods do yuo have on the car? the base map for the Apexi is for a decatted rx-7 apparently. I dont know if this includes filters, downpipe, or intercooler changes. The best bet is to have it mapped specificly for your car that way you know its running how it should.

Im gonna put in some octane booster to finish off this batch of fuel and then try super and optimax to see what readings it gives me.  The plan was to take to WGT when my next service and mot is due, have a decat downpipe fitted and fully mapped.  The only mods I have are a back box and a tax disc holder!! (so still both cats in)

Even thought its a UK car you are running a Jap ECU so stick with the high octane stuff.

Thanks Keiron. Sounds entirely possible, gonna put some booster in it to finish off the tank and use better fuel next time.

And thanks to all else â€" im gonna post up the new readings (if that’s ok?) when I have given her a run with octane booster!

Cheers, Ricco.

Ok been into town today and got some octane booster (had to settle for Nitrox cause I couldnt find any Millers.) Put 3/4 into my half tank ful of 95ron and I have 142 knock - worse!!  :reallymad

I think im gonna ring pip and get it looked at - I have about 80miles to travel to see him so does anyone know If I can get that figure reduced?  I have doneabout 40miles so far and hoped it would settle down.  :confused:

It also seems WORSE now apart from when im accelerating or on idle!  :confused:

Looks like im booking her in to see Mr. Specialist!

Think that would be the best bet matey, has it been showing this much knock since you first installed a commander or has it only recently gone high?
If its always been high I would say its likely nothings wrong with it other than a knock sensor fault, sure if it was knocking a larger problem would have developed by now, but like you say let Pip have a butchers or at least give you his opinion, be able to put your toe down without worrying then

Can you keep us informed as Im interested, to be honest I dont think theres owt wrong with mine but the readings dont seem quite right....

thanks

BTW not sure how good octane booster is compared to higher octane fuel, I know its a few peoples opinions on here that it doesnt do a lot.

Never used it myself so dont know, just what I heard so thought id pass it on

[Ricco_04]

If I remenmer (which is pretty dam unlikely for me!) then I am going to ring Pip on monday to get booked in and for a bit of advice.  If he can tell me anything usefull over the phone then ill post it, otherwise will have to wait till he\'s had a butchers.

True, I think higher octane fuel is better - have to take some of it out before I go to WGT and use some of Shells finest!  :cool

Thank you all for your help  :wave   :cheers

Had a word with Pip today (yes I remembered!  :cool  ) He kinda put me at rest. I described when I was getting what readings for the knock and he said he was almost certain that there was something loose or malfunctioning or else the engine would probably have blown up!!  

He agreed that octane booster wouldn’t be all that great and to put in super anyway (for all the reasons from you guys.  :god  )  So I\'m temp booked in on Sept 15th to get the necessary replaced. If I had more money then I would have more stuff done (spoke to him about trust downpipe, sports cat and a session on the rollers for a remap) but I\'m definitely heading in the right direction!

Keep you posted what they find wrong.

Rich.
