TMS28F512 - what chip to use in place? (Marelli IAW. 1AP 10)

[VTS_Tibi]

Hi Guys,

In the future I will have to tune a few Magneti Marelli IAW 1AP 10 ECU found in the Xsara VTS / 306 GTI6 2.0 16V.

Most of these ECUs come with a TMS28F512 some with an ST28F512, and I also have two which have been remapped previously, using an AT27C010.

I have a Willem GQ-4X to do the job, which can't do the TMS28F512, so I'll have to find a chip to replace this.

What kind of chip could replace this - preferably one which can be rewritten loads of times!?

Thanks,

Tibi

Well, I would need an other brand, like ST, as my Willem can't do the TMS :)

Treat it as Intel 28F512 and you will be happy.

gq4X work 100% with 28F512 any brand
you can use any 28F512 or 27C010 or 27C1001 , or 29F010 or 29F1001 or 27C512 you have the choice
please be sure your gq4X is up to date check newer soft .

on gq4X soft try with other 28F512 and check your adapter contact

You can't replace a 28Fxx by any 27cXX eprom the pinout is different.
You can use a 29F010 for 28F512 by connecting pin 2 and 3 togheter and program 29F 2x with the same file.

Be sure to use a proper 32p PLCC to 32pin DIP adapter to read/write the 28F512.

i did lots with 29F010 never got problem

the other i do them all over obd ... with the spi system

Sorry but you wrong .
what i have write is from my personnal experience on peugeot and citroen old ecu and msa15 tdi ecu .

is not write i have read or heard by another one , so i can certified 100% that it work ,

To replace 28F512 with 27C010 or 27C1001 (and 29Fxxx) are possible BUT NOT with 27C512

@Kennfeld
I find it hard to believe you can flash the 1AP10 by OBD with a 29F010 flash.
The 29F010 has 5v programming voltage and the 28F512 12.5v.
I made this mistake myself 1 time and also blown an OLS300 emulator in the past.

And yes indeed 27c010 should also be working.
I should even be possible to program it in circuit but never tried.

VTS_Tibi, I gave away my gq-3x sometime ago and no more following them but you may get to know how to add TMS28F512 menu, in the sw folder and editing the file 'device.txt'. check here (http://www.mcumall.com/forum/topic.asp?TOPIC_ID=5196)and similar threads too. have fun to try.

and more: if try, set ID="89B8", the ID for TMS28F512A can't find it for TMS28F512 but found a few 1AP10's are always version 'A'

easytech programming obd it's with the original chip inside without any soldering

i do with spi from evc ;)

[easytech]

Yes with 28F512 it's no problem but as you write in your previous post it is confusing for other members.
I made this mistake once in an ecu which was previous 'tuned' with a 29F010.
Then by obd flashing, is was fried...

[VTS_Tibi]

Just to add a bit to the story, I tried an identical ECU and Willem read it without a problem.

The ECU I tried first, which made me write the original post is completely dead!

Hello everybody

Prepare to reprogram some VTS and the question to you what tools today will read and program the FLASH through the OBD connector or SPI so that they do not have to desoldering 28F512? Is there such a possibility?
The said EasyTech supports Magneti Marelli IAW 1AP.10 not tracked. Besides, OBD has only Xsara VTS Ph II Ph I and has the usual diagnostic connector.

Thank you in advance for any replies
