Tuning 1.2 8v cinq info ?

[djindiano]

The crudity of it is that the first injector just can't supply enough fuel when the engine is on boost, and the whole thing is too damn dumb to control one injecrtor.

In practice, those set ups use 2 fuel regulators, the original (for the original injector) and a second, aftermarket one (for the boost set up).

i have decided to go with a mpi engine because i found a lad that has all the parts i need to make it work but i no i need the mpi loom, engine but do i need the ecu to ???? and im getting a 1.2 16v block so i can strip it and wen it is striped i will strip the 8v engine and start rebuilding the 8v engine the lad i found is like a fiat man lol he has the hole mpi car there so im going the go and strip everything i need out of it on the week end

Not if you're going turbo -- the SPI one will be OK with the Honeymaster style piggy back, or you can go aftermarket.

do i have to get 1 of them or could i not just remap the 1.1 ecu ?
and i am turboing it so i will need the mpi one

and you make a good point when it comes to the mpi and spi. mpi runs safer

 

[fingers99]

The point really is that although all the NA ECUs understand atmospheric pressure, and most can be rejigged to understand more than 1 bar, they can't really understand boost as such and so can't do retard on boost. Woj may have some more detailed, better, ideas.

Of the MPI ECUs, the late MPI Sei one is the best (but I'm not sure how amenable it is to reprogramming). I hear that the 2 plug Micro ECU fitted to the Punto Mk2s and the early MPI Seis is pretty hopeless in all respects, but that the Mk1 1242 16v Punto one is very good in all respects.

But a good piggy back, or an aftermarket one, will be the best and safest bet.

My car has a chip that supposedly retards timing for boost but i suspect that its just retarded all the time and why its a bit crap off boost compared to my old cinq turbo which was basically same setup but without said chip..

 

[djindiano]

i just want to make sure it will run right because i have done my fare shere of turboing cars and them blowning up but they were only turbo for fun thats why i dont want to mess this up


and the fact that this car is very important to me

The piggy back system Honeymonster uses is probably the best value for money. But any odf the aftermarket ones should be fine.

Probably a good idea to find a well thought of local rolling road and ask them which ones they're happy to set up.

Prob the best bit of advice so far, last thing you want to happen is get it all together and then have noone that can set it up properly..

where can i get a good piggy back from ???

 

[fingers99]

Poland. But they do adverise on eBay, too. See Honeymaster's thread.

It's an ancient, super strong, heavy old lump of an engine.

It's really too heavy for a Cinq (I suspect it may be too tall, as well) and will make it understeer like a pig. A lot of fabrication required to make it fit, too (going on the similar Uno Tub engine).

If you like, get the Punto and rebuild it as a Punto. 200bhp is no real problem for them. But don't pop it into a Cinq.

never mind stupid moment lol i looked up a few things im sticking to my 1.2 lol

 

[djindiano]

dose any one no of a turbo kit going around ???

 

[fingers99]

Very rare to see them. Essentially, they're not much use anyway -- a T15 (pretty much the wrong turbo), a bit of badly welded pipework, a suspect chip for the wrong ECU an absolete MF2 and a fuel cut defender.

If you want to do this properly, you may as well start from scratch.

its just for the moment i need my car on the road and i will be making my own one with a ct9 turbo

 

[fingers99]

Then put it on the road as a N/A car.

You can't do rolling development (of that order) on a turbo. It always leads to disasters.

i cant try lol done it before

 

[fingers99]

i cant try lol done it before

And, by your own admission, fooked it up big style. There's about a month's fabrication involved in the placement and packaging of the stuff alone, and you want to do it with an obsolete Japanese turbo which no one has used before..............

thats what makes it better that no one has done it before iv had toyota gt starlets and lots of them i no with power there turbos are like so im just going to see it it works and i have one 1.2 8v engine there to go in for the moment and one engine that i am making a high boost kit

It makes it better in the sense that the Mona Lisa was better because no - one had done one before. BUT you ain't no Michaelangelo.

i no with power there turbos are like so im just going to see it it works

You're so unlikely to be able to do it like that -- it's not about power (and the engines are different ones anyway) but about the sizes and ratios of the turbines

and i have one 1.2 8v engine there to go in for the moment and one engine that i am making a high boost kit

To do it by trial and error you could well get through 20 engines.

I see you're determined to do it your way (which is the same way as you've tried it before).

But, the sane approach is, I repeat, to find a 500 Abarth engine and box, and put that in. It'll be faster and more reliable than anything you can conjour up yourself. And there are none in Eire (or in GB) yet. Instant stardom will be yours.
