more turbo questions

[trdfxgt]

im going to be running my blue top computer for a start until i can afford a aftermarket ecu i have a sx fpr and some 2ltr skyline injectors which ill set up for the feul side of things but how do i set up the map sensor and the timing advance ??

[trd__levin]

dont do anything till you have the right ecu.

[Fraud]

As above.

[Punter]

I know those ^^ probably aren't the answers you wanted, but it makes the most sense if your straped for cash you don't want to explode your motor. just run n/a untill you have your setup sorted.

just my 2 cents anyways

fisrt of all you cant run bigger injectors with the standard ecu.
and u want the timing to retard not advance.

[JamesM]

u can run bigger injecotrs on the staNDARD computer.and if u use say a 3bar map sensor from the st205? (i forget) but the injectors need to be the same impedance as the standard ones.. it does work. its a cheap arse way to get around aftermarket computer tho. a few guys in the states do it. (its on the net somewhere)

you can run bigger injectors on standard computer, this trick is for people who's not willing to pay any money for their mods and want big power.

You have to get a lot of paperclips for a start.

You use yoru paperclips and plug it up the injector holes so it wont' inject too much fuel, then you run a length of wire to your cabin to the injectors, now this is the tricky part, when you think the car needs more fuel, you activate the injectors yourself by applying 12Vdc to the injectors, but you have to have a quick hand and good timing.

For the ignition retard, try putting a paperclip inline to each spark plug, the resistance present in each paperclip will cause a delay in firing, hence ignition retard, but you have to have a trial and error to get the correct igntion timing retard, it takes time.

But in saying that, what you do to your car is what you do to your car, I take no responsiblity, although I heard from someone at a pub once that his uncle jack did this and got 450hp, he was running a CT26 too!

he also had a shiny new muffler that apparrently pulled all the girls

[Bazda]

hey thats something new, i never thoguht u could put bugger injectors in cos it would run rich down low and foul the plugs up. But i suppose that map sensor would help that.

[JamesM]

yea it can be done.. i did alot of stuffing around.. but the injectors really need to be exactly same impedance (mine were a bit off and caused me headaches) but as logn as the map sensor is of the same type (0-5V) and reads the same voltage at idle as bluey map sensor then is ok.. but its rough.. i think thats right.. i forget..
is it worth the stuffing aorund? no..

[Jebus]

A jaycar DFA will let ya do Fuel injector swaps, and theyll work sweeto on stock ECU.

[1598cc]

put the ecu in cel mode or

get some check valves to your map sensor, and run 2 extra injectors before throttle body..

Careful Akane! There's people here who might take you seriously...

I vote for this solution. (where's my template rant about "if you can't afford to do it right, you can't to afford to do it at all" when I need it. oh, hang on, I just said it...)

[ants_ae92]

This is the kind of thing ae-86_lad is talking about.

Although they used 2 bar map sensor and almost double the size of injectors of his standard ones. And this was only light bolt on turbo application.

Hope this helps.

[trdfxgt]

ok it seams clear i will need to go to a link strait away but is there not people out there with standed blue tops running psi ?? how are they done

[JamesM]

yes using the cold start injector, computer in diagnotic mode. timing at base 10deg, drove mine like that on 8psi for abotu 1 yr.

[trdfxgt]

can you discribe how i get thet injector running ?? as i just find i can learn alot more about this if i do it my self

thanks heaps for any help

[JamesM]

placing a reisitance.. (use a 5kpot) in series with the sensor signal back to the ecu (engine thinks its colder as u turn the knob (increase resistance)).
