Your way off.

I also run sequential injection, and I can stand +- 20deg injector timing at any given rpm/load/InjPW and not see a change in Lambda/AFR/torque. Try +-20deg ignition advance.

As...

Didn't realise it was optical, 24 is accurate enough. Quite neat packaging.

Just to be clear, THE MOST important event the ECU controls is the spark timing in relation to piston TDC. Not so...

Accuracy is the drawback of such systems. If, and big IF you can package a 36-1 tooth trigger wheel in the space on the end of the cam shaft, you are getting one pulse every 20 deg of crank, as...

Some EMS can use a toothed wheel turning at half crank speed. So on a 36-1 wheel, the ECU will be looking for one missing tooth per cycle as opposed to one missing tooth twice per cycle.

How did it fail, i.e what were the symptoms? Loss of power, bottom end knocking, rod out of the block?

SOme systems have only cost as a drawback and that is a key factor. Functionaluty wise, there are may systems that deliver all and more than we need, but you pay for it. One of the key cost factors...

Wise! Folks on here are good at spending other peoples money

I have JE Gp A replica pistons, Arrow rods. Arrow shim under followers, 292/284 cams and Evo valve springs. Yes, $367 from TMS...

BMW don't supply replacement valves, never have. The only options are aftermarket.

If you make an adapter for the spark plug hole that allows you to feed in compressed air, you can change valve springs without pulling the head. Shims can also be done without pulling the head.

Am I correct in saying, you have added 30-40 points of fuel to achieve the same AFR as the pre CF airbox tune?

When you talk of 30-40points, how does this translate to injector pulse width?
...

Pin 9 on connector C101.

If you have your stock chip put it back in, you should be OK.

The FQS is in the DME/ECU and is accessed trough a small hole. Do a search and you should find it.

An air leak can only happen when there is a pressure delta over the opening, i.e atmospheric pressure is greater than intake pressure. When at WOT we are removing the restriction from within the...

Definately!

Also, like advised by others, check for air leaks. Although, at WOT any air leak has little effect as the DME runs on a WOT map which is independant of the AFM reading.

Moke sure...

Do you still have the Fuel Quality Switch (FQS) functionality with the JC chip.

If it does, set it to 5 clicks clockwise.
...

Unless you have some sort of strange piston design, then this cannot happen as the closest the piston comes to the head (as stock) is 1.2mm in the area outside of the valves.

Aftermarket chip?...

The Stratos was a replica kit with an Alfa twin cam.

If you want to see a serious Stratos replica...

500hp!

I was invited to attend a local car show today (Sun 19 May)

Only about 80 or so cars. I took some pics of some of the interesting stuff.

E Types and F Type. It is huge!
...

Don't bother as the rattling you describe is a result of the reduced mass of the flywheel, not the balance of lack there of.

To save searching...

I have a 18cm runner airbox for 48mm TBs and a snorkal. The box needs a coat of clear coat and there is a little damage on the snorkal, but nothing major.

If you PM me your email I'll send pics,...

Any pics of the workmanship?

That was my source of info during my engine build.

The 320d has far higher engine torque than the s14, so capacity shouldn't be a problem.


If you look at the speeds in gears @7500rpm with 4.10 diff
1 32
2 58
3 ...

Shouldn't take any longer than a day, 8hrs if the tuner is good.

It is expensive, budget $1000 for the chip and dyno time, but it is cheaper than a spun rod bearing!

Have you checked if you...

I'm tuned at 13:1 AFR at WOT. There was no extra power available when richer for me.

I see your point regarding the engine spec. This will be down to the confidence the OP has is that the engine...

The drop in AFR is most likely because of the map you are running on you chip. Either an Evo2 chip/ECU or a WAR chip will give you the best chance of fixing the issue. It is also likely that you...

If you have the TBs off can you take a pic of the intake ports?

Steve

Stock quench= 1.83mm-0.584=1.246mm

CP Piston quench= 1.83mm-0.381= 1.449mm

Difference=1.449-1.246=0.203

Target block thickness for stock quench = 282.66-0.203=282.43.

If I were decking...

Fit a helicoil insert.

Should be able to pick up a kit with a drill and tap for about $30.

It seems to me that the new piston is suspended on the pin from the old piston. As good a fit the pin is there will still be some play which will allow new piston to sit lower.

My thought is to...

Adding cam timing will not help low end lethargy. The Evo cam gear will help in the mid range as it gives more overlap. Do you have a graph to see how it compares to others?

Steve

Not the most accurate way of measuring. Try putting the piston crown down and measure the height of the pin from the surface.

Either way, an increase is quench clearance is not desirable. BMW MS...

Ideal.

Re-profile your trumpets and have a custom fuel/ign map written.
