Tuning turbo time!

Tuning turbo time!

Good stuff :) (y)

Get that map sorted soon though. Gazzaman and Asteris mave posted some maps in the MS section for turbo's. I'd imagine as soon as you hit boost, your running far too advanced and lean. Don't wanna kill it before you get too drive it :D

yeh I gotta pull the wideband out of my car (i never fully wired it in anyway). i can then start tuning it on the drive.
wouldnt of damaged anything its running supper rich up top and fixed advance :)

im gonna look at other maps now

I was really surprised how quick it picks up. i was expecting it to be slow when blipping throttle cos of low compression and back pressure. maybe the flywheel is lightened?

but im REALLY glad it runs and sounds healthy.
the boost control and turbo timer dont work for some reason but should be just the crappy wiring.

there has been a serious electrical gremlin running thru this car! both boost controller and turbo timer have been toast!

on both a large diode right on the 12volt line has burnt out. luckily the boost controller worked after i replaced the diode but the timer is totaled as the diode burnt out the heat melted a IC that sits under it

I guess im lucky it was the timer which aint needed and cheap.

also the alternator dont seem to be working.
 
it keeps the engine running for a short time after turning off the ignition... there actually not legal and i would never leave my car running unattended!

Did a bit of map work today! used gazzamans maps but he said hes never drove it so not really much use. theres a few dead links on the MS thread now so im going to PM Asteris and see if i can steal hes :p MOT on my other cento tomorrow :eek:

edit: you git edited your post :p

not according to Peter (oldschool) they arent :shakehead:

He says that you wouldnt want to push any more than 120-130bhp from them.
to quote: "The 16v rods are weaker than the 75 rods. I would not use them for anything serious"

The new'er 16v rod are able to run 180 bhp. This is proven on a 1242 16v turbo running 1 bar boost.
This setup have beed on the road in @ 3 years now with no problems regarding the rods.

What i dont get is that Tricker says hes almost getting 200hp from hes engine? has Oldschool tested this or is it just a guess?

I never claimed that my engine can produce nearly 200 bhp - the highest i got from my engine is 134 bhp running 0.8 bar boost.
I don't see what Oldschool has to do with this..? Is he the only one to trust regarding power figures?
My engine was tested on a calibrated dyno, so I trust the figures are correct.
If Oldschool were the only one to make a correct power figure then he would be a very busy mann.. ;)

Does oldschool actually do tests on them or is it just guess work??

I'll be using 16v rods in my rally engine, n/a and a limit of about 9k, wanted to lighted the rods but people just told me not to, not heard of any failed 16v rods, and not many people have actually lightened rods but still say no to it
 
craigb244, Tricker has fuelling for around 200bhp not that his engine was producing that. Though my engine is producing just over 160hp at the wheels, which equates to around 190bhp, with a fair bit more than 1 bar boost seen in the intake manifold.

I feel he applies research/testing beyond it's bounds and comes up with silly answers. As for lightening the rods I'd go for it if you have an cheap & plentiful supply of spare engines, else find a good engine builder to take a look & see.

The only reason i mentioned that was because, like everyone else on the internet, i passed around information coming from someone else. (although tbh he is a respected engine tuner, so i would tend to believe what he says)

Obviously that info was incorrect, if you and StoneNewt have been there and done that :)

ahhh that could of been my fail!.
talking on fuelling...

pulled my fuel pressure gauge from the N/A and fitted it to the turbo. i noticed that it shows around 2 bar when its not running (primed) but when its running its just over 1 bar and when you rev the car it dont change!

I know on my N/A the pressure raises. as vacume drops off.
I pulled the hose from the regulator and the pressure never changed much, if at all.
anyone know much about the regulator on the mpi p75? i know for a fact the turbo wont work at all running only 1 bar of fuel pressure!
 
Iirc the p75 runs at 2.5bar fuel pressure well im 90%sure and the punto85 runs at 3bar
which map sensor is being used on the turbo set up btw if your using standalone management a rising rate regulator is not needed as you can map in extra fuel?
As long as the ecu can see boost
Zak
16v rods can be made lighter only slightly though
 
the p75 ran at 2.5 and 3bar, depending on which fuel rail / year it was. i will dig out the details if anyone cares :)

raising rate is still useful even when mappable ECU, it allows you to inject tiny amounts of fuel at idle due to lower pressure, but enough on boost due to higher pressure. (you just need to bear it in mind and compensate when mapping)
