Chipped Ecu's

[kerim]

i just wanted to know more about chipped ecu's. I have read that you can burn like base maps into the chip, but would you still have to get it tuned, or you can just run off that. Can someone please explain abit more on how these work. I understand its like a diy style of engine mangement, but is it recommended?

Kinda like crome... but simplified method is:

1)do a dyno run
2)make tweaks to base map
3)burn onto eprom and plug into ecu
4)Repeat step 1
5)repeat steps 2-3 if required


If you just need a base map then just burn that....

how easy is it to burn the basemap, can it be done by anyone? I am assuking you need the burning tool

equipment ain't really cheap.. even eBay sells em for $200 plus... pretty much the rom burner.

Crome software is freeware afaik... and the cost of the chips + mounting ZIF socket for your ecu

***EDIT***
as for mounting i just ended up getting this kit... was cheap and everything needed was there as well as instructions... didn't come with enough solder wick though which is an absolute must!!!!

Chip burners are about $40 bucks on ebay for the Willem item. Moates.net sells a far simpler version for around $80 from memory. Far from $200. Can be done by anyone, and takes about 5 seconds via USB.

One big disadvantage of using chips over a real-time system is that you must turn off the engine everytime you make a change (plus the fact that you must go through the effort of actually burning and changing chips).

Crome has a free version, but Crome Pro, which has datalogging is not free.

Thanks... will look into the $80 USB one

i am looking at buying a already chipped ecu, so if i use a usdm P72 ecu, would i experience any problems?

I wouldn't chip an ECU.. the cars come out the factory with ECU's tuned to run the car at an optimum performance.. if I really wanted to, i'd tune the car instead and replace the stock ECU for an aftermarket one.. chipping ECU's will only put the car under more strain and shorten the life span of some of the parts in your car..

^^ i dont see how chipping the ecu will put more strain on your car.

its pretty much like making your current ecu into a programable one. you overwrite the values on it for your new setup, be it FI or NA. the only downside was said above that its jsut a little more hassle.

... yeh whatever...? -_-

I don't think i'm on the rite track here.. but i thought tuning an ECU is done so that you decide how your engine performs for example.. like how much air and fuel go into the engine for example..? correct me if I'm wrong.. thats why I subscribe to this forum, so i can find out more about hondas..

The ECU doesn't control how much air goes in... however figures out how much fuel should be injected relating to how much air is being sucked into the engine and when it should spark etc etc

Chipping a factory ECU in no way "put the car under more strain and shorten the life span of some of the parts in your car"

That statement couldn't be further from the truth

"the cars come out the factory with ECU's tuned to run the car at an optimum performance"

Again simply not true... They are tuned to get the best millage and generally smoother power delivery; not necessarily peak power nor torque, really depends on the car however a top end super car would be more power/torque
