heard about this lastnight... bodging the loom up on an MFi ERST engine so it runs off 3 wires...

not even ueing an ECU...

so what exactly do you connect up, and just HOW bad is it...

im gessing youd never get it to run "right" as you'd surely have no overrun fuel cut and no WOT enrichment... either that or it's run rich as fuck everywhere except full throttle?

and presumable it's be det city if the ACTs got too high?

 

sounds like a plan

 

 

eh?

 

 

That sounds right up your street Jim.

Someone order a Fire-Brigade visit to Jim's house.........

 

i dont wanna do it i just saw an XR2T with it done lastnite and was surprised it even ran let alone drove

 

theres an xr2 for sale on here somewhere with an rs turbo lump in it . that has`been 3 wire tricked . not sure if its a very good idea tho

 

probably the same one brad...

 

it does work Jim, Tel had one and ran fine, shame the chassis had snapped where the wishbone was held on otherwise itd have been a quality toy.

oh yeah and the sills were filled with newspaper

 

my old xr2 turbo was also running this set up,,

was a magenta colour 1 which was featured in revs years back (about 97)

run fine while i owned it but i heard it took the bloke who built it a few engines to get it right

was a pukka little car running about 170-180bhp with no problems at all in the few years i owned it

but be warned no 1 wants to touch em mechanicley wise for fear of blowing em up

 

Chicken
so glad you have heard off it

as far as i know its been around for years
anougher one off my m8s has a xr3i done the same way too
he has no problems with it either

Chicken my m8s xrt2 is running about the same bhp as you old one,and his also has not let him down mechanicly

 

ok explanation on how they work please and how the ignition advance ect works as im stumped

i can see the fueling is done via the metering head but all the sensors and TPS was taken off

so im asuming its a vacum system and if so whats the actual fueling like,

not a dig at ya mate greg but my mate wants a xr2 turbo and hes wondering of the whole picture

what wires ect are swoped

cheers

 

Sounds more dodgy than buying a gold watch from a bloke called Dodgy Ken in the alley behind the pub

 

no worries ginge i know it not a dig

be perfectly honest i not got a clue how it works just no it does

 

steve its dodgy BUT the car does work and so cant be that bad ( well except for the speaker wire )

but i cant understand the ignition though

 

Ginge

 

Crazy kids

 

well it didnt seem to help the stereo much

 

 

 

Your car becoming too reliable for your liking, Jim ??

 

i just spat my drink out reading that

 

How come everybody has failed to ask the most important question?

WHY?

 

Well, that's sort of my 'implied' question.....

 

The pain in my ribs

 

Every day should have SOME laughter in it......especially at Jim's expense

Glad I could be of service.....

 

Agreed Matt, but sometimes on here, you have to speak slowly

 

Yeah, I type slowly in case *** or a few of the others decide to peruse the topic

 

no pon the reason why is quite obvious , its cheep and does seem to work for certain aplications , cant argue with that as the peeps who have had it will agree it works , just like 5th injecotors ect, i wanna know how it works as there must be a down side more that just theres no saftey stuff, i was thinking of is the igniton correct ect as i can see why ford would fit all that ecuand stuff when a bit of speaker wire would be ok ( hypotheticaly speaking )

i got banned from the saxo website for saying that the evo7 coolers are not needed for 7psi as there aint gonna have that high acts' to cool down at 7psi and also got a slating for my talking about narrow band afr gauges being pointless in turbo aplications and a trader on there claimed i was talking shite and he said that a alpha narrowband IS sufficiant to set up a turbo cars fueling ans when i asked did he use one he never replied and i got banned , i felt like the guy people laughed at when he told the everyone the world wasnt flat but round

they was like "nooooooooo, hes telling us stuff i dont wanna here, get rid of him, hes ganna cause a revolution on saxo's ,grap ya torch and pitch fork and lets ban him "

 

 

So, basicly your running an engine with no engine management?

Just the K-Jet meterhead to provide the fuel, no warm up enrichment, fixed ignition advance, no knock/high act spark retard etc.........it may work, but it cant be big, or clever!

 

So you are using a very expensive carb ?

 

That is the way The Grp A RS16i Touring cars ran, they also had a seperate switch to turn on/off the cold start valve

 

so what is this bodge up then?? how ya do it?

 

phil, thats what i'm thinking... but surely you'd get NO ignition advance/retard? as i thought the ECU did all of the spark calcs? i mean its not got a vac capsukle on the dizzy or nuffin

 

Exactly Jim, it will just run whatever the dizzy is set to. (Ie, constant X degrees.)

So the car will essenitally be setup for WOT only id imagine (if it isnt, may end in tears )

 

Baring in mind though the turbo engine had been in the car best part of 30,000 miles i am led to believe. Although its obviously a very crude way of doin it, it DOES work, as chicken said he ran his like that for a few years.
Still the application of speaker wire in the engine bay wasnt too impressive

 

but is chickens latest car mfi and hes now going cossie management

whats that tell ya

 

It tells me that it works and does the job depending on what you want it for. It allows 180 bhp or so, how much power would you want in something that weighs as much as an anorexic quaver!
Saying that if i did buy it i would convert it to a loom just saying though it does the job. Like 5th injectors, it works! If it aint broke, why fix it!
