Good luck :)

Well with this type of standalone ecu, you typically discard the OE item, and replace it solely with the new one. What i tend to do is take the original loom, strip all the sheathing etc of it, and remove the actual control wiring (i.e. all the wires connected to the ecu multiplug)...this...

How come you need to retain the OE ecu?

your best of manually checking the crank sensor really. any immobiliser fitted?

:)

dunno if i agree about the ear tho...guaranteed its not as could as 'proper' electronic detection, but its good enough for most cases. at the end of the day...u can go on forever in a spiral of "this device/method is better...blah blah"...where do u stop?? where the budget allows usually.

lol

"that" frequency wont be constant tho...it will vary with operating parameters and conditions? do you do that on all cyls Ben? It boils down to the operator aswell....u cant beat a "million dollar ear"...best tool in the trade.

did u find the proper fuel map Mark?

twin turbo is the way for a v6! they sound foookin awsome! on the Nobles, the open airfilters are positioned to the left and right of the engine bay, behind the "bulkhead"...so they sit either side of the cabin, behind ur head! when ur coming off boost, u get chirping alternating between the...

The air-mass meter are prone to going on these, worth checking.

whats the spec Freddy-four-fingers?

Your "fuel" one above lol

and what curve is that?!

as regards the 2deg window...if u were using det cans, you would pick the onset of det a couple of degs before you would with the naked ear (if`at all)...so it really depends on your det detection set-up. I have cyl pressure transducers which would be handy for experimenting with s**t like...

Its all relative...when you say overly advanced, advanced from what point? Theoretically you would use MBT as the main reference for what you are saying. If you advance from MBT, you further increase peak cyl pressure (and temp burned and unburned), and as weve said, negative work. This in...

I'd still be tempted to see if you can tweek it.

LOL, just read my previous post...i didnt mean it should actually mirror a torque curve...i meant it should peak at the same point!

It depends who mapped it...and how badly they have done it :)..... Ben is right mind, it should level off...and It looks like that peak in ign advance at 4400rpm shouldnt really be there, and thats why there is a dip in your torque...i.e. it IS over advanced at that point, so increased...

Max ign advance is theoretically at max brake torque....alla your graph, you'll notice it resembles a torque curve. This figure for timing is known as the MBT timing figure (MaxBrakeTorque). It varies with load and speed, but follows the trend of torque output due to volumetric efficiency.

Lads...THIS^^^^^^^^^^^^^^^was the question. The question wasnt "should i try slicks?", or "are slicks any better for handling?". He has come to the conclusion HIMSELF that he wants to try slick tyres.... HE WANTS TO TRY THEM!!! Posting comments about driver ability and training is...

Where does an oil cooler come into it?? His oil temps maybe spot-on as they are...why cool them?? As for slicks...yes they generate more grip....they will allow u to push the car further. best thing to do mate is try them...if something breaks..fix it! if u dont like them change them...

Yup, too much retarding from MBT timing figure is just going to be crap for performance. Also over compressing an engine is going to increase mechanical losses. Also, mass produced engines are intended to run in most conditions, including extremes. An engine running a given high Cr may run...

bent valves guaranteed

Mark, ignore Fred mate, he blows turtles! Give me a shout if you want me to come and have a look at it with you. Craig

There may be a vague, in-direct relationship...but its not close enough to be used as a quantifiable measure. Too many variables...gear ratio, drag, frontal area, etc etc etc to make it anything close to definate.

Higher combustion efficiency Chris. Thermal efficiency actually starts to deteriorate when you get past C13:1 as the volume:surface-area ratio of the chamber reduces.

Certainly will. £180 drive in/drive out from me. Or £150 on exchange basis.

my mates 182 made 167bhp when it was 12months old...go figure!

Neither does terminal speed lol!
