ecu chipping?? has anyone ever tried

i was wondering if anyone has ever tried one? i used to have a e30 bmw a few years ago and was so curious of these chips i had to try one. and to be honest did notice a slight diference, not in power but it smoothed out the flat spots.
has anyone tried one in a subaru??

Re: ecu chipping?? has anyone ever tried

I assume you are talking about one of the plug and play chips? If so wouldn't recommend one myself. Though not used one myself, haven't heard much good said of them. If you are after a new ecu you'd be better off either getting your current one re-mapped (if possible) or getting something like a Simtec/Ecutec and a bespoke map done by a pro. This will ensure that the ecu is getting the most out of your car and, more importantly, your car is running safely of which there is no guaruntee with a generic plug and play chip.

extreamly lucky to say the least.


the basic idea is its a one map fits all cars, the chip is just the method of transfering the data.


the theory is sound, on alot of cars, but scoobs are different. each has such a varying degree of differences witht eh way it runs thats the map has to be built up from scratch to make sure its running right and not dangerous to the engine itself.


none of the big tuners use generic maps, excluding ppp and subaru of course, and that answers the question.


you might say y?, surley the tuners want to make the most out of you as possible. you cna make more form generic than you can custom.


shall break the costs down not real world just examples)


lets say it takes a mapper 4 hours to map a car, 50 an hour.


so 200 mapper cost.


dyno time wear/tear plus operator, say 25 per hour


so 100+200 = 300


some programs require license fees, say 200


so 200+300 = 500


then add vat at say 15%


575 all in, with no profit at all, just costs


so for 100 maps = 57,500


say you pay 600 for the map then thats 30 profit so out fo the 600 thats 5% profit


on top of that you have buying the dyno, buyng the laptops, software etc etc but thast common on both types.


generic chips,


4 hours mapping time for first map, then adding to a few cars to make sure ok add another 4 hours (at same 60 an hour)


480 + 200 dyno time


applying map to a car, say an hours labour, 25


there fore 100 x 25 = 2,500


plus 680/100 = 6.80


therefore rounded down each car costs 30 to map.



if you pay 100 for a generic map thats 200% profit.


and that in lies the answer.

Re: ecu chipping?? has anyone ever tried

I run a z4 ecu in mine but i did buy a zero sports 'base map 2' chipped z4 ecu from 'the bay'. Never got round to trying it properly before my engine troubles started. As/when it's sorted i'd be tempted to take it to my local tuner ( jeffers ) and plug it in and see what hi opinion is? Idealy i'd like to find out a bit more info on the ecu/map of the chip. I.E, what injectors i should be running with it etc etc. Might try it at some point if i ever get the car sorted :-(



Internals of standard z4 ecu


Internals of the zero sports z4 ecu


If anyone has any info on it then please let me know!

Re: ecu chipping?? has anyone ever tried

I am looking for a Z4 ECU if anyone has one going? (Or any 4 plug pre '96 ECU with the spare slot)

BackWheelBoy - What's most interesting about that "uprated" ECU you have is that the J1 resistor seems to be intact still, which should render the chip entirely redundant. To use the chip map that needs to be cut / removed, otherwise (correct me if I am wrong) its just a standard Z4 ECU?

Or maybe my "uprated" ecu does have the resistor cut



May sell my standard z4 in a couple of months if this one proves to be any good

Re: ecu chipping?? has anyone ever tried

Ah ha, I stand corrected!

Drop me a line when you decide to sell the Z4. In the mean time I have been offered a 3B. This is off a classic WRX Wagon.

I know the standard boost etc is one of the lowest out there etc.....especially compared to the Z4 but does it matter which 4-plug ECU I use to chip for a V1 sti? (as long as its prior to 97/98 ECU)
