Technical mk1 punto 1.1L Chip Tuning

[MadMan0]

Hi all,
Following on from my post in the punto section i was getting no response so thought i'd post here.

I'm looking to remap my ecu for a fiat punto 1997 55 s 1.1L spi (Uk)
I wanted to do this for exp with a blank chip, copy the current map to the new chip then "tweek" it.

I've done mapping before but never a whole map.
Currently trying to a EEPOM read/writer that will work with the fiats chip, but i don't know what chip they use

Does anyone know?

Why out of interest

Why not? For experience he says, seems legit

Madman0 - I just swapped the chip in my Sei for a mckcritch chip, I'm pretty sure the ECU's are the same as the Punto55's - it's a 28pin chip approx 36mm x 14mm.

Does anyone know if this chip is suitable?
£11 for a new blank chip (mirco controller)

Then copy the Fiat chip memory over?
Might be worth buying another ecu to avoid damaging my current one:idea:
Lots can go wrong when you don't know what you're doing .

The engine i mapped had a performance ECU which you could just plug in and change... I Wonder if that will work with the punto's ecu...

Soz, just re read your post! wrong size etc.
Did you happen to copy the code written on top of the chip?
Or if you have the standard chip out and about, could you post the code/number on top of the chip please, so I search for a spare / blank one?
Thanks.

It's hard to read but I think it's:
MID - SL
16FME6
CHK 1ED6

wow, there are a lot of free maps ready to download already
MK16F.EB 2449 (tuned chip code)
No luck finding a blank chip to match codes above yet.

I've just noticed printed on the back is also C5014664 and P802

I think these are what I need?

The read/writer is still looking costly though, I will keep looking for a cheaper device, either just the circuit board or try to get the uni to support me

Looks right, but both my original and replacement ones have a sticker on the top of them so can't tell if they're identical. Might be worth asking gazzaman2k as he was doing chips for the Cinq/Sei, might even work on the P55

I've had a message asking to post the links to engine maps,
When i get a free hour i'll try and dig out the links, but in the meantime you can always use "Google" to find them

I'm being trained on the rolling road this week at work and will hopefully get to meet someone who has exp in remapping Eprom chips

I will also try and get to use the rolling road to settle the debate as to weather or not the K&N air filters change the BHP of the mk1 punto No promises though

I'm the guy who asked about the maps . I gave up looking for them and started re-mapping the car myself. I'm still in the process of tuning her up and tested some tweaked timing maps today with good results :slayer:.
