what did you do to your micra today ?

Drove 120miles to pick up a little present for Charliedoing another 400 for a little something else :laugh:
Tomorrow
here,s an old dyno graph of mine that shows the 2 runs in closed loop (above the arrow, where the ecu is using the lambda signals to adjust the mixture to near 14.7:1), and 1 run in coldstart mode/open loop (arrowed, where the ecu is running from a stored map of around 13:1 a/f/r,s)

there is,nt much difference in power output, but you definately dont want to run lean under boost
the downside is that you end up running acceleration enrichment all the way up a long hill in 4th or 5th gear
Srill confused, so closed loop is where it makes 14.7:1 for most of the time, then at a certain speed (what is the speed?) it changes to open loop with a richer 13:1 map taking no notice of the lambda readings? so when you disconnect the speed wire it always tries to run at 14.7:1, that has to be preferable for standard does it not?
Of course I could still be completely wrong :doh:
I drove to Hastings today to take some parts off of an AJ4 Super-S. I got the best bits. :grinning:
Nice job Hoopdub. What did you source the turnbuckle from?

Looking for the overall diam of the alternator belt section on the pulley (larger of the two belt sections)...currrently got about 8 psi on the stock size, just curious how much bigger it would need to be to add a couple of psi
Seeing as i should upgrade the maf, its got me thinking haha.

the outer rim is 118, and the pulleys are 110 and 88 mate

Suppose you get what you paid for, going to have to rethink the tubby
Not worth the hassle anyway get a t2 from a fiesta plenty about and fairly cheap
1 busted blade karl ?
Yeah and a chunk missing from the prop
Was thinking t2/t25 but I only want a small amount of boost
karl the turbo i sold you is t2 from s12 with t25/t28 flange.
I think its set to 7 psi standard,
I know but there's a tiny problem...... I can't find it anywhere :down:

People normally replace them for t28 iirc from the s14 that's why prices are high as the s13 boys want them as well! I was looking at a turbo from a diesel but I wasn't sure on the waste gate as they operate differently to a petrol dont they?
found this on a tdi forum
Very nice, EXCEPT almost no TDI models have a wastegate.
Our cars use vacuum actuated variable vanes. Different tech to accomplish the same thing.
Advantage of variable vanes is that boost can start at lower RPM and stay more or less constant for flatter, wider torque curve.

yeah as frank found out recently
lol :grinning: now rectified with my new GT15 (Y) (from a honda diesel)
plenty big enough for a 1275cc petrol, members tend to fit a big T25/28 designed for a 2.0 petrol engine, and then wonder why its laggy
eye they can be welded up tho and use an external one or just mod a petrol one to fit. was just thinking if karl is wanting low boost then a kkk ko3 would be perfect but like you say also faffing around with waste gates can be a pain.
I only want low boost so I don't blow up the carbs :grinning:
