Chip identification?

[spink]

How can we get 2 maps to work with a chip. Eg both set up for different fuel?

Is this to switch between petrol and LPG?

Yes the LPG will idealy need 2-5 degrees more advance or maybe just more boost... We will see. Anyone any pictures or the fancy chip with extra address lines fitted?

Is your ecu 3b, or AAN/ABY/ADU? What is easy for 3b, it's quite problematic for others .

im pretty sure Des has a S4 aan from previous posts.

Yep aan. What about something like doing away with the altatude sensor. Then replacing it with 2 resistors and a switch. Eg if the ecu can then relate 2 different maps to these different altatudes???

After a bit of info please.
After a long wait, my 1.4 bar generic chips arrived yesterday from MRC.
I'm no stranger to opening the ECU and swapping chips and understand the orientation they need to be inserted with regards to the small notch, boost chip is on the PCB with the map sensor and fuelling chip the other PCB.

Only one snag with the MRC chips, they have no identification on them whatsoever!!!. Not even a sticker over the small window on the top which I'm led to believe will render them useless if left in the light (not sure if that's correct or not, but they are sealed up until they get fitted)

So, question is, if I unluckily inserted the boost chip in the fueling chip socket and visa versa (remember, I have no way of knowing) will I do any damage to the ECU? or will it just obviously fail to start??
Of course I could get them the right way round first time, I've a 50/50 chance. But do I risk it?

I'm not to keen on sending them back, as after one or another (slow communication and bloody postal strikes) it's taken since my initial inquiry on the 25th sept until now to actually get them in my hand.

Thoughts?

TIA

Exactly the question I asked Mihnea. Answer if you get them wrong it doesn't start but does no damage.

is there an easy software to look at the chips (in case you have them in the pc as i do now) with an easy way to understand them?winOLS is quite difficult to understand what you are seeing.I would like a boost/rpm scale for example and something similar for injection as well

should the turbo chip write the 257 and not the 256?does this mean that it will not work???
