mildly built 2.6efi + tco6 turbo

[Manelite]

hey all im bored and just going to bung a tco6 turbo on my car jst to flog around in

its running a stock ecu so it should be fine for low boost im talking about 7psi

how do u guy think it would runn

[Billsy]

it will die a horrible death. i tried turboing the std ecu.. above about 3-4 psi it was running dangerously lean and the ecu doesnt pull timing for boost.
after 2 days of nanna driving i went aftermarket. far far better even off boost.

also the std injectors max out with the thought of boost.

[Manelite]

well the stock ecu should handle it with a gm map. i jst happen to have one..
as the air flow meter and o2 sensor should tell the ecu that there is more air going thru the system so it will ad more fuel

[75wagon]

I've never played with these (so this is probably worth nothing), but wouldn't that depend on the parameters that the factory allowed in the ECU's settings?

Meaning: They would have designed the ECU for the motor they were building and for the application required. So would they have allowed for performance increases like you are suggesting? Why do people who modify injected car so often go for aftermarket adjustable systems if the standard could handle it?

well the stock ecu should handle it with a gm map. i jst happen to have one..
as the air flow meter and o2 sensor should tell the ecu that there is more air going thru the system so it will ad more fuel

I don't know what a gm map is? Please enlighten me....

ok a GM map sensor is 2-3bar map where a standard is 1bar

[Billsy]

magnas dont run map based fuelling, its all done by the AFM, and the tune simply isnt made for boost

theyre designed to run lean for power and economy, if you add boost to this you generate massive combustion temps and it will detonate due to excessive timing and lean mixtures. and the injectors arent big enough for the extra fuelling requirements.

by all means do it and see what happens, but you can get a second hand ecu for around $500 or a new megasquirt and then youll be laughing

[Manelite]

im sorry to say but my magna is running a map and if u want i can take a picture of want

and if i want to go big injector i got a set of 600cc lying around and a 450hp fuel pump

question how is your engine "mildly built"
and if your gunna ask for advice from people how have done
it wouldnt it pay to listen?
if your mind is made up and you have all the spares why not
just do it
cheers stealth

[Manelite]

mildly i class as a full acl rebuild with 20thuo over bore and flat top pistons and a reco m8 head

i just believe that it will run jst want to know poeplw thoughts

as a stk ecu has a 1bar map which will let the system to handly 7psi 2bar lets it run 14.5psi

i know that the magna runs a map

[Billsy]

im happy to be shown wrong, where is the map sensor? id love to see see a pic of it, and where the vac line runs to the manifold.
also do you mean 1 bar map sensor as an absolute pressure? if so then it doesnt go to 7psi, otherwise it'd be a 1.5bar sensor. 2 bar reads to 14.7psi (100kpa boost, 200 kpa absolute)
a one bar map sensor will only read up to Zero
also, std ecu + larger injectors wont work well either.

[stealth]

not to mention that 1 bar is 14.7psi
and a 1 bar map senor wont read positive pressure
but yeah mate prove us wrong!
cheers stealth

lol standard computer... lets see that mild build go bang...

guys, as a mod, i feel its my duty now, to ask you all to stop with the burn, and leave the fella alone..

its quite obvious he knows what he is doing, and dont really need our advise
especially from ppl like stealth and billsy, as its quite evident that they do not know what they are talking about

both of these guys have never made any decent power figures from an astron
or had any experience with efi turbo engines
so yeah, i wouldnt take their advise either mate..

you go ahead and totally fuck your engine on your own

i like you brett

hahahahahahahaha cheers

i know it will fail but i have seen a fresh motor run 1bar with a aftermarket last 6 months and it only did a head gasket

[Manelite]

you guys asked too see the map senor and the vac line well here they are

[oldskool]

WTF what are u talking about man?

[Manelite]

WTF what are u talking about man?

that is a picture show the map senor as asked by Billsy

[oldskool]

do you think thats a map sensor?

[Billsy]

ummm Dude....

that aint a map sensor. its just a fuel pressure solenoid

[Manelite]

do you think thats a map sensor?

well you tell me what it is

[oldskool]

you guys asked too see the map senor and the vac line well here they are

just going of what u said here, dont get to upset

[Manelite]

i jst got owned hahahaha

i know what that for it raise the fuel pressure for a hot start

haha

[slo]

omg

Now what was the reason you were banned from Aussie Magna :wank:

being over active and saying how fast my car can go..

it ok im not going to be putting a turbo on my car but i am getting a 4g63 box loom and ecu for 800 so win,

[dvsfin]

i smell roger cordia...!

LOL OH JESUS CHRIST! In the 7 years of being a auto elec ive never seen a MAP sensor like that one! Better hook up the 3 bar GMH one might give u better enrichment on startup! LOL u wernt being serious though?? Better go do some research before u go running ur mouth buddy no one here is gonna take u seriously from now on not that any one was from the beginning. LOL stock ECU and 3 bar map sensor!!! im showing the guys at work this one...

[GC75]

lol as funny as it is, chill out guys.. there is proving a point, then there is taking it beyond the point and criticizing even though he was set in his way lol.
