was Dan listening to his Ipod instead of his det cans during those runs?

 

My personal belief (and having talking this through with some other techies) is that Dan is responsible for that damage. Dans no doubt going to throw a fit about this but I dont care as Im fed up with these things being hushed up on the forum and others going the same way.

 

Unless Dan can give a full technical explanation why its not his fault and why he isnt paying some or all of the repair bills then Im going to have to reconsider the trader membership he is operating under.

 

I cannot accept a member having their engine blown and the mapper taking no responsibility.

 

that should make things interesting.

:goodpost:

 

Totally agree, an explanation of how it was not his fault is needed.

....1.75 bar, standard internals, normal fuel.... mentalist.

 

LOL :D

 

Really sorry to about your engine matey, i remember how gutted i was when my stock tubbies blew and that's no were near as bad as this! :(

 

Out of interest what sort of rebuild are you going for?

Thanks for this level of support, I think you make some very valid points and I think the fact he has stated that he was told by me to map ' a safe map ' and '1.5 bar' must stand for something ?

 

I was not aware he was a trader on here ?

Not going to comment on the specifics of this case, but you can't simply say X amount of boost will cause det. It completely depends on the ignition advance you have. You can run high boost with more retarded timing or lower boost with more advanced timing. Det will occur when you have the timing too far advanced for the boost you are running. So you can't just say that 1.75 bar on 97 fuel will cause det - it may be completely fine if the ignition timing is ok.

Well should that not be part of the mapping set up ??, just asking as I really dont know too much about mapping

Oh yes, definitely. You start really conservative and then advance it until you get maximum torque or start to hear det. Not saying it was or wasn't the mappers fault - don't like commenting when I don't have all the info. Just that there's a load of people throwing their hands up at the thought of det at high boost on standard fuel when that's not necessarily a problem. I wouldn't want to run a standard engine at that high boost anyway whether it dets or not!

Well I am going out now, but the car will be at my house for anyone who can offer a hands on opinion and inspection if something can be learnt from that, I will provide a cuppa !! that offer is also open to Dan and he would be more than welcome to come over and discuss his thoughts as he has not yet seen the internals as they are

True you cant say fuel + boost = det, but you can say that 1.75 Bar on a std engine isn't going to have some consequences;) especially if det isn't being monitored properly, also the mapper should have full control of the ignition and fuelling during the run, so at the first sign of det it can be rectified

However its not as simple as to much ignition advance for the boost, as to little advance can also have the same result for the given fuelling.

Agreed, but would have thought 1.75bar (blipping to 2bar) on 97RON would require so much retard, it would verge on antilag!

But as you say, without all the facts, maybe we should step away.

Do you have access to the AEM ECU and software as you may be able to download some logging data, depends if it was enabled.

 

The AEM utilises the stock knock sensors and as well as det cans you can see the 0-5v output of each sensor, when I am playing with the AEM I always have these on screen as well as det cans. Once mapping is finished you then configure and turn on knock control.

 

If you asked for 1.5bar then I dont see why a 1.55 or 1.6bar boost cut was configured instead of mapping the upper cells, there is no reason why your boost should over shoot what you have requested.

My GF is going to kill me if we dont leave now, I have the plugs and all the bits , will post up pic tomorrow if that helps

 

OK no problem, just interested, as they will help to show just how bad the det was depending on the type of plug;)

go out and try and forget about you engine for a while:)
