well least they didnt bat an eyelid at my decat and exhaust just told me it was a bit loud lol but still 170 for an A service on a clio its stupid

 

sorry this question has nothing to do with the project but i'm hoping u experts can help, driving along today in a punto then the temp gauge and rev counter start going all over the place then the car dies and the code light comes on, the engine turns but wont start, any ideas?

F.I.A.T
Fix It Again Tomorrow

Could be anything. . .

 

thanks and the fiat will be going soon

 

I don;t think here is the right place to ask or to answer but..

If the temp gauge and revs were all over the place, sounds like a coolant leak.. sensor for gauge and ecu temp see air then water etc as the air bubbles go through the system.. ecu sees cold when air goes through and puts choke on hence revs increase, then sees water temp and revs drop as it turns the choke off.

If it now won't start then it sounds like the leak is due to head gasket or you have warped the head etc etc..

Check your water level and look for cream in the oil and oil in the water etc..

Sounds like you probably killed it though, best thing for the poor Punto.

not on my thread please

 

thanks for your help, it was a faulty ecu according to the garage

Hijack over

Any update David??

R.

 

a few e-mails suggested something was happening...

Alas it would seem not.


Gathering dust is it David ?
wish my fooking clutch would hurry up.

Andy

 

emails from who?

David

 

Subscribe to this thread e-mails.....

What's happening?
Ar you still having a break from it ?

Andy

 

Dear Mr.Wallis,

I will have a little spare cash this weekend and i was thinking about pumping it into the leg.

We need to have a team-talk about 'the plan' and purchasing some bits.

Mr.X


P.S. Sold the blue saloon for £1000 (with the gearbox still popped out of its mind). 'I love it when a plan comes together'

 

Thats criminal

David

 

Fuzz..

I need to get on with it now..

Its been a bit difficult as weve been building a new workbench in the back of the garage.. which will give me somewhere to fix the spare gearbox etc.. and make car parts..

Will be sorted soon

David

 

And my in-car PC will be 100% finished "soon". *cough*

 

fitted new coil last night.. however battery was flat, so will test tonight.

David

 

wwaahhhayy

Good luck.

is that it done then ?
when's the next roller session?
Did you finish mapping it, last I heard you were on your way down my neck of the woods on a marathon mapping session. ?

Andy

P.s persuade Steven to get back here and post.......

 

Ive tried talking to steven.. at the end of the day its his choice.. he has two kids and a wife which come before the car..

Anyway, we mapped it a bit more.. didnt really touch timing, mainly fueling.. and it hasnt been mapped in boost areas... however once ive built a little circuit to take a

9:1 - 19:1 0 - 5v output to a linear 10:1 - 30:1 0-1v then im in business to run fully closed loop.. circuit is designed, bits are at home.. footy tonight though.

Will try car and then see about mapping if it works.

David

 

WHHHHOOOOOOOOOOOOOSSSSSSHHHHHHhhhh !





Andy

 

9:1 - 19:1 is the AFR range that my wideband will do.. you get a linear voltage between 0 and 5volts representing the above..

i need to then rescale this output to pretend to be 10:1 - 30:1 with 0 - 1 volts.. (which is what my ecu wants..)



David

 

Crystal

Andy

 

Rev counter now working..
Missfire seems better / gone.. just need a road test..


also..

My solution to test for wideband.. as designed by my dad..
http://www.wallis2000.co.uk/newproject/op_amp.xls

or..



works down to 8v.. Just operating temp to look at now.

(See note on resistors for 9:1)

David

 

With the new coil?? and the MSD?

R.

 

new coil and msd and little wiring change, and ecu cal change.

David

 

just sorted board layout.. left on table for parental consent :d

off to bed.. brain hurts..

offset null, inverting null.. argh..

David

 

*splat*

****, my brain's just dribbled out of my ears...

Brilliant news mate, really hope this works. And execllent news about the misfire, fingers crossed!

 

dunno if I posted these pics so...

time for motivation plan...

WOW



Pretty talented person, and so many helpful friends. You certainly have some foresight to be able to do that.

Do you have 2 subarus?

WOW!!!

 

Just the one..

 

some more pics.. A couple on the previous page too..
