DTA S80 PRO on 5 cylinder

[UrS4boy]

1 5 2 3 4
This is running like a half a V10 so count only every other cyl and you get 1 2 4 5 3

The Audi V10 has two five cylinder banks, e.g. Left = 1,2,3,4,5 and Right 6,7,8,9,10 (correct me IF I am wrong).

The firing order is 1-6-5-10-2-7-3-8-4-9

Every second cylinder of the *V10* is 1-5-2-3-4.

I don't see how you can take this yet another level of "skipping".

dspl1236 seems to be getting a lot of stick for something he is actually right about, like Audi CQ said the DTA manual looks very strange suggesting to wire the coils in this order...

1 5 2 3 4

This is obviously not the firing order of the engine but it is the order the coils need to fire when running a I5 in batch fire, aka wasted spark.

"Oh dear" i said wasted spark and inline 5 in the same sentence again

This is just a small misunderstanding about firing order vs. coil output nr I quess.
If running a DTA in batch mode it's running as half a V10 and the setup in the manual looks very strange at first, but is correct

Thank you

I almost hate to say this, being a Motronic fan, but IF you had to go stand alone, I think you would have much better Audi 20VT support (here and elsewhere) with VEMS. This includes but is not limited to Marc S. at EFI Express plus many others here and on other US Audi forums.

Seems like the guidance you are(n't) getting from DTA is causing you some of your problems.

Good luck. I'm done. (I know *that* will make you happy)

Dude take it off the forum no matter what ecu you use the physical firing order is 1 2453
It can transposed on aftermarket to say 45312 but the order for the Audi I5 is the same
It's quite offensive for dta to give their opinion of a firing order set in stone by Audi

[dspl1236]

i have had 20vt's for years. installed several standalone systems. 1.8t, i5 20v, v8, vr6....dude i get it. firing order it doesnt change...but configuration from system to system does.


I came into this DTA thread to see if one of these guys follows what DTA says or they tossed the instructions and went with the real firing order

If you have no experience with DTAFast systems then do not answer. there might be something in the firmware..... I dont know....hence why I am asking. I only posted in here since you brought up the bogus firing order DTA says

Finally somebody else is thinking the same as me. dspl1236 has become (or always was) a complete time waster because he will NOT grasp the most basic information when it is thrown in his face, i.e. the correct firing order. He still keeps asking, like timing order is an arbitrary thing and some people use one firing order while others are using another.

These engines, their crankshafts, their cam shafts, have all been designed to work with one and only one firing order, 1-2-4-5-3. Period, no substitutes.

Other 5 cylinder engines, e.g. some Volvos, some GMC engines *might* be different than that but if they are, their crankshafts and camshafts have been designed accordingly. dspl1236, if you are listening, please, please get this through your thick noggin'.

Harsh, but rightly so. There's no helping some people.

[UrS4boy]

The fact that you have to ask what the firing order is suggests to me you should forget about tuning or even working on your engine in any way, period .

I understand all that can be gained by running a cam sensor is a small ammount of economy at lower (cruising) revs, not really what you want in a rally car.

I know this is old, but, the cam sensor is required for:
* Knock control (to determine knock window and cylinder)
* Decreasing the load on the coils by a factor of 2. On higher revolutions, running two sparks and two dwell events can overheat the coils, because it's like running the engine at double RPM, and the coils were not made to function at 14000 rpm at high boost.
* Misfire recognition
* Continous camshaft adjustment (to get feedback for current camshaft position) and it's diagnostics

I would say 1-3 are useful for any car. Out of that closed loop knock control directly affects the performance and safety, as using it, you can always run maximum possible spark advance. Without it you have to leave a respectable margin of performance untapped, to be sure nothing blows up.

bringing this back. what firing order are you guys using?

FUGGGGG. Why won't you believe me? 1-2-4-5-3. It's cast right on the head so muppets can't F it up.

[taycoss]

What coils are people using? I have a set of denso units from a honda s2000 which fit well. Would there be any probs running these?
