    Update time...

    I've now got a fully working reflashable ecu with a standard 7201(EM0005) map on it.

    I've reflashed it with a 7202(EM2005) rom unfortunately the car will turn over but won't start.

    Which leaves me stuck with a reflashable ECU and nothing to flash onto it other then the stock rom (if anyone wants to examine the stock pfl rom see post No.1 of this thread).

    Is there anyone out there with a metal cased Mines ECU that would be willing to take a look inside? Unless someone who understands these things can decipher the 7201 rom I've got nowhere to go other then trying to clone a mines ecu and examining the differences between the stock map and a mines map.

    Hi kinky, is this still via desoldering of the EEPROM?

    Edit: Ps. might be worth making this a sticky thread mods? It has potential to be hugely beneficial for us PFL owners once the nitty-gritty is sorted

    After some late nights myself and Nutter_John have mapped out the ecu.

    All the theory is done the 7201 is as tunable as the 7202.

    We are now working on offering a mines like ecu swap service with a menu of different tunes to choose from...

    We expect to be able to offer this service in 3-4 months

    Pricing estimate is £100 (with a £50 deposit to be refunded on return of your original ecu) - this is CVR4 member price.

    I plan to offer up some dyno proven results on my own car within 2 months.

    Nutter_John is managing the map side of things so will probably be posting on the topic soon.

    Yeah some very long nights have been spent on this but this is a huge step forward . A lot of hard work was put in by Rich doing the intial stages but after we got his car running on Saturday it was only a matter of time until we cracked the life code of the 7201


    Ok the plan is to get 4 different maps so that the customer can choose what level of tune they want ,so you could say different stages (stage one up fuel cut , remap to 0.8 bar , little timming etc etc )

    Hopefully in the future we can also start to look at doing ALS , LC ,CEL KNock , but this will take a lot longer as they are not the same processor as the 7202 so this will be 100% new code

    What I have found is that it is very very unlikely that the 7201 can be flashed via ecuflash as the chip does not have the same built in boot loader nor does it have the logic the flash the eeprom

    please post any question regarding this and we will answer , but one huge step foward

    Custom re-maps are a future product and has already been discussed with a UK tuner

    Let's not lose sight of the benefits of the factory ECU, here:

    The NutterAfro flash is about changing the factory maps.
    This means you retain all the knock-sensor-related goodness of the factory ECU. Same (to a lesser extent) with the fuel cut.

    So you're not taking a huge risk with each map: no more so than buying a Jap car and running it on 97Ron. There is, of course, the possibility that you may encounter a horrific problem...but that possibility exists with an MBC.

    If you're doing it properly, you'll have a boost gauge, wideband and potentially some kind of knock monitoring fitted already. Right?

    I think it would also be a good idea to have someone in New Zealand or Aus also doing this work - as firstly it would be closer and safer for us in NZ/Aus to post ECU's to, I'm a bit wary of sending electronics halfway across the world!
    Also those of us in the southern hemisphere seem to get different tuning/power results to those of you in the UK/Ireland, so it would make more sense to have someone here tune the ECUs to our conditions.

    Good idea. All you need is a computer geek, a tuner, somebody competant with electronics, a VR-4 owner and a clear idea of what you want to achieve. There must be these elements available in NZ/OZ! I'm expecting

    can i make a suggestion, and this would be only if the UK people wanted to do it.

    if on the off chance the the maps would be the same for UK and NZ, OZ cars then can i suggest that the UK people get to know and trust a local representative in NZ and OZ with the required electronics expertise. then the programmed chips themselves could be sent across the world and then fitted by said trusted representatives in the NZ and OZ locations.

    but this is of course just a suggestion and it is up to the developers if they wish to consider this.

    it is still very early in the 7201 ECU map sale and distribution life so it will take a while to get the process established and efficient. but i am sure lots of people will take them up on there product.

    and good luck to them.

    Bye for Now!

    Let's keep this thread on track re information concerning the 7201 flashing process. The freedom of the information/knowledge behind the flashing is no longer a topic for discussion here at the present time.

    Thank you!

    Next real update will be early March when we have some RR results to show , we are finishing getting all the tooling setup to enable us to do this on a reasonable scale

    So to keep this on Track,if i find ive got a 7202,i can reflash it myself,

    -if i have a 7201,i can take it oiut and send it to you and you remap it to my taste?

    Keep us informed please!

    I would expect this to be simply order your PFL ECU from Kinky Nutters Inc. with your required map, and then send yours back to them?

    Obviously these are my wildly accusating claims and not the real process involved, until otherwise proven by the peoples involved.

    well we are corrupt so the more you pay us the quicker you get it

    it all comes down to how quickly people return there old ecu once they have our one
