Technical 1242 8v SPI Preparing Engine For Turboing

[SlinkyCinqi]

Hi Guys,

Tried the suggestions given, attached is the msq with the settings used to create the log. The first cranking on the log was done with the coil packs what I believe to be the correct way, then the second spell of cranking was done with the coil packs reversed.

That weird MAP thing is still going on too, this is getting worse and worse lol

Thanks again guys

i wish i understood any of that lol, sounds interesting. I don't even know where the mf2 is mounted in my turbo

Under the carpet in the passenger footwell by the door I think from memory..

lol, cheers jamie.

Glad to see ur working on her again mate, any joy?

Hi Gaz mate,

No luck as of yet, gonna have to check out whats going on with the engine itself me thinks, due to the odd jumping MAP readings.

Anyone got the definate timing marks for the 1368 16v?

Thanks again guys

you will be in need of the timing tools to get it correct

but you need all the pistons level (mid-stroke) and on the side of the cam carriers there are 2 allen head caps you can remove, there are two slots machined out of the cams where the locking tools would go into

Hi Ash,

I've set up 1242 16v engines before, sounds much the same process, I'll double check it using 4 equal length rods and an allen key in the slots.

Thanks again

Hi guys,

Gonna turn the car around and check the timing tomorrow, have put the interior back in (done this last weekend) looks one hell of alot better and has spurred me on to get on with it!

Any other things anyone can suggest for me to check either physically or in megatune, then I will report the results on here as soon as I've checked them.

Thanks again

Hi guys,

Checked the timing and its spot on, so must be something else. Any other suggestions from looking at my datalogs? I'm out at the car now.

Thanks again

Some logs from today attached guys, tried Asteris suggestion of taking the ASE and WUE out of the equation and just using req_fuel to get the car running, fond that I also had to adjust the cranking pw when I looked at my first longs and the pw was still much lower than the re_fuel value I had set.

Car still popping and spluttering, where the spikes of positive MAP pressure are, that is where there is a loud pop from under the bonnet, it seems to be sparking at totally the wrong times i'd guess, but god knows why. I have tried reversing the coils again as well whilst just using the req_fuel value. There is a log of this too.

After my attempts at cranking the exhaust manifold was also stone cold.

As you can see on the logs also, my lumpy MAP reading seems to calm down if I open the throttle more. I was just going to have the car idling by cracking the throttle for now, how far have people got their throttle butterfly open in order to obtain idle?

Thanks again guys

Run through the engine specs and details again, as I can't be bothered to read back the entire thread.

The title says spi, if it still is spi, you have injectors set to 4 for a start.

It's going to be very difficult to diagnose without being there, you really shouldn't be having so many issues.

The diggest, in fact, only real problem I ever had with MS is the VR circuit. It looks ok on your's but due to MS1 its less good at picking up spikes from the VR sensor. Have you played with the trimming pots at all?

the map signal will be smoother with the throttle open as there is less restriction and vacume so smooths out the dodgy signal

you say there is no effect from swapping the coils over. this means the timing is out by huge amounts.

the only time ive ever had mine back fire thru the throttle body was after removed the HT leads and had two leads swapped my mistake (example: coil 1 firing cylinder 1+3)
you NEED to have one coil on the two inner cylinders and the other coil on the two outer cylinders.

make sure that is correct.

you only get firing thru the throttle body when you get ignition while the intake valve is still open, that would require over 100 odd degrees ADVANCE lol

indeed, I wouldn't worrk about the map either. I fyou are worried about that though, set it to alpha-n and it won't use the map in the equation at all, just TPS. I ran my sei like that for a while, tuning is harder for over-run etc however. Like I say, i think may is fine but if it#s playing on your mins, just don't use it.

Also, stick some timing marks on the bllock, and check timing with a stobe.

 

[SlinkyCinqi]

Hi guys,

Thanks for the advice, I'll get checking ASAP.

And kristian its 1368 16v running pink stilo injectors and punto 1242 16v coil packs. Marea 1.6 16v tb on punto 1242 16v inlet mani.

Thanks again

Lenny

Edit - yes kristian I've tried adjusting the trim pot for the vr signal

 

[blu73]

you must a fair few bits lying around by now, are you absolutely sure you got the correct crank pulley on it? I'm not sure what the differences are from engine to engine if any buts its an easy mistake with the right kinda consequences. I have a new big book to read after which the datalogs may mean something to me but right now its just wierd numbers lol.

Hi Blu,

I've got the cinq sporting pulley on it, and ground away the engine mount to make it fit.

I'm just waiting for my new timing light to arrive, which should be coming today then I can check the spark timing properly to make sure its sync'ed up with MS.

Thanks again

Lenny

 

[randomizered]

Is it a variable strobe or a fixed one? If it's variable, on some you have to take into acount the wasted spark and half the readout.

If ya using the cinq pulley, how you getting the crank sensor to line up ? OR have you got a non air-con 1.4 16v engine ?

[SlinkyCinqi]

I thought after I'd posted that, I think I might be using the original pulley lol, I'll check it all after I get my timing light. And I'll check what pulley I used, think engine was non-aircon as I didn't have as many issues as others with crank sensor lol.

Kristian - timing light is variable but has a feature for wasted spark engines so it only shows every 2nd spark.

Thanks again
