Either way 2 or 3 its still a middle cylinder and there is no way it ended up with significantly more air on that design of plenum.

Besides if it WAS a distribution issue, Karl would have heard cracks of Det from that cylnder during mapping.

 

Chip,
isn't number 3 the leanest on a cossie?
just wondering what can cause this,fuel pump,regulator,injector??

 

I only ask the question, as when Karl first mapped Jim Green's car, it was done one AFR ONLY , hence my question .

 

Karl will need to comment himself then I guess.

I can only assume he maps the way that I do, with det cans on.

 

SiB, gutted for you mate.

Looks like I may have been the last to see your car on song for a while then, Shame cos she certainly was shifting!



JJ

 

I have seen Harvey map an engine on the dyno WITHOUT using any
form of det monitoring and it was a BIG power engine

 

I hope he was doing the low speed mapping at that point then, as I have never seen him do this without det cans, unless he is sitting beside Ahmed (who then wears them instead) .

 

Gutted for you Si!


Alex

 

5000 to 7800 rpm, 600 bhp peak power - yes it was low speed.

I did comment about the lack of det checking and I seem to remember he
said something like " I can tell when its detting as I know the dyno sound changes"

He may very well be right as he knows his own dyno best but it worried
the hell out of me as I was adjusting the ignition map from instructions
given by him.

I realise this may sound like a stirring post - it isnt. My point is I do think
experienced tuners may have some kind of "second sight" or intuition
when tuning.

 

Karl knows his ignition maps and i am 100% confident it wasnt an ignition problem that was wrong in the map.

....deffo looks injector to me..but we will wait and see if i am correct

 

Mike......FFS stop putting Harvey on a pedestal

 

Well it's something I have never seen before, but det cans are certainly something I would not be doing without on the road, as you have wind and tyre noise to contend with.

The only person I know who is like that is one of the guys at AVA, and he stands in front of the engine when they do a dyno running listening for det and he can apparently hear the faintest crack above the fan / engine noise, as he has attuned himself to it and can even tell when it is borderline .

 

I'm the one that needs that to prevent neck ache .

 

I get the BLAME again



Mike, just to set the record straight: That evening I was in the Silver Saph Stage 1 (T3/355 light green injectors/NMS Gunship live mapped), and all I did was floor the throtle in 5th gear at 80 MPH until near 150 MPH (indicated) and immediately backed off having pulled a good 6 to 8 car lenghts on SiB car. Even if i was in the Es Cos I dont think I would have held it on WOT any longer TBH. Simon (SiB) also backed off as soon as he got past me.

 

Doug,
The only point I was making is that the car needs to be tested to the most extreme speed / load that it is ever likely to achieve, any less and the second you go above that - GAME OVER. This is something I have had happen in my own experience, so know how important it is .

Tested to worse case scenario, it doesn't matter WHAT you throw at it, it will be safe. This is why I always think the BEST place to map is on a long runway and NOT the road. Since sticking with that, I haven't had any engine failures....

 

Harvey mapping a 600bhp car without DET cans You sure you dont want to change tuner Mike

 

I'm on the phone to Mark right now .

Just got this message though - "Sorry, the number you are trying has blocked your number. Please don't try again later" - WTFs that all about ?

 

ROFL Try texting him instead

 

Hello all,

Long time since I've posted but during my lunch time browse of the net I thought this was worth a comment.

An interesting post with lots of comments.

Sib's car was fully checked for det and AFR at all rpm's and boost.

However what has been failed to mention is that's Simon was booked in to bring the car back to me due to a running fault which had developed some time after I had mapped the car.

I advised simon to not drive the car as he clearly had ECU signal issues. In spite of this I then read on hear he has been thrashing the car!!!! The only fault here is simons right foot when he knew the car was running with faults!!

 

kARL ANSWER YOUR TEXT WILL YOU..i want to send you parts

 

LOL okeedokee, will do Phil!

 

Si you muppet .

 

So Simon could have prevented this engine loss by taking the advice of his tuner? Hindsight is an exact science

 

Not good.

 

A valuable but fucking expensive lesson to be learning!

Si B, a knocklink *MAY* have warned of this and id worse considering for the new engine.

 

Oh dear

The truth be told now.

I still feel for you Simon. Its so hard to resist that kick in the back.

Steve.

 

ohhh no si what have you done!

 

assuming you can cram them all into the engine bay, where the hell would you mount them on the dash

 

again with the cmplicated words
what's a knock link when it's at home them?
is that what they were trying to get in mission impossible?
everyones gone all techy on us non nerds and no one is explaining

please?

thank you

 

a knock link is a device used for hearing knock or det on an engine. I have never seen one in operation, but i assume it has a series of lights that light up and when the sensor detects knock on your engine a warning light is put on to warn the driver. Its a bit like having det cans but without the need for them on your head, its a gauge with a microphone type device, listening to your engine for you and warning you at or just before the critcal moment.

 

thank you kind sir for the explanation, some more question if yu would be so kind

it's basicly a mic on the engine?
almost like the old school "stick a screwdriver in and to your ear" sort of device yes?
so how do det cans work then?
are they actual cans that youput on your ears (like it's being implied in some posts) or ar they actual bits that do measuring the same way as the knock link?

 

To further Dougs defence, he was not with us at the time of death. It was just me, SiB and Phil2400.

No-one else around

 

And we we were only doing 70, as any more would have been illegal.

 

sorry to hear this Si, not good to hear when you have just got the running gear sorted.

money,money,money.....

 

Bad luck Si hope u get it sorted soon


Paul
