Ignition only table?

[andy198712]

at WOT mine is in and around 95......

i dont really know what would happen, any ideas? interesting point

What happens when you hit a cell over 100 Kpa with the map stopping at 100? Does it just continue with the highest known value?
I'm naturally aspirated, and hit well over 105 Kpa during low 90 Kpa barometric conditions. At sea level I would be touching into 115 Kpa cells.

Yes.
On MS it uses the last row for anything beyond it, so for example the leftmost column is your base fuel for cranking.
(use: playing with that, cranking fuel% and base timing is what you tune to make it very stall resistant)

On MS2-extra v3.3+ (may be in 3.21) and MS3 there is an option to do "MAP averaging" (high rate oversampling +averaging) vs. timed sampling, makes tuning MUCH easier, with fixed timed sampling the resonance caused my MAP to go from ~112 KPA to 85 KPA in ~250 RPM, them slowly ramped up to 105 by redline.

MS3 also has a table for timed sampling vs. RPM, haven't tried that yet, as the averaging works peachy.

good to know, i was worried the world would end if i went off the end of the table rpm wise lol not that my 1200 can rev that far! but will let me fine tune further

I've just found this thread, it's made some good reading.
Thanks

cheers bud! been good, especially with the price of fuel over here!!

I daren't look anymore, I need it so essentially I'll pay for it end of story

quick translation from £6.37/imp.gallon = $8.47/US gallon

Same! i dont bother to look at the price, costs me about £50 to fill up my beetle, but i try not to notice lol

38.58mpg....

[andy198712]

37.13 MPG

Been using my eberspacher a bit....

Awesome numbers Andy, I am jealous!

[andy198712]

these are UK numbers and in a slow 1200 bug i'd happily loose 7-8mpg to have a fast engine!

i've still not even checked the tyre psi's! which is pretty rubbish of me.

found your blog so interesting! i'm thinking of goin the same route with TBi's

[andy198712]

38.44mpg

Desperate to make 40 lol

Might try the super unleaded...... That or buy a wide band

A set of low rolling resistance tires may be in your future, and they DO make them in narrow 15" sizes.

If faced with only putting 2 on, put them on the front (if same or narrower than rears) as driven wheels allegedly have ~no rolling resistance.
(Or at least that was AUDIs theory at one point, came up when they developed the UrQuattros, and they still went JUST as fast as 2WD despite the increased drivetrain losses)

I have just about gotten back to ~35 MPG (US) with my setup (went from MS2>MS3+changing WB setups) and the next step is going to be a 914 5 speed or LRR tires. or both, when the tires are in need of replacement.

Tire pressures and wheel alignment really start to be critical once you are trying for >35 MPG.

14point7.com has a new $99(OK, $105 this week) sealed analog-only flying lead WB system that just came out.
...including sensor.

this is from cold, no throttle
