Stock Ecu Difference's

[Blizzerd]

Whats the difference between the stock ecu's of our s2 stagea's

23710-0V800 and 0v801

i have a 0v800 - Mines ecu

but if i get a 801 what will happen ?

manual or auto? Is your car modded? I dont know the codes, but all manuals ecus are interchangeable. Same goes for auto. Just cant use auto in manual car and vice versa

I have a series 2 rs4s, the 801 is also manual ecu

pod filter, zorst, i-color

whilst they are interchangle and the car will start etc

some MEC chip types are not, you may find if you get the wrong MEC chip type, the car runs OK and idles etc but as soon as you drive it, it becomes mega sluggish and performs like ASS

i had this on my series 2 GTST with a remapped ECU, the remap was done to suit basic mods and i connected it up, took it for a spin and it ran like a bucket of crap

turns out the MEC chip type was wrong and i had to use a different MEC chip number. ask a remapper what the MEC chip type means, from memory the guy in sydney taso i think knows what it means

Cool, thanks so much, looks like ill be getting an 800

Your mines ecu will probably have the speed limiter removed (all JDM cars are limited to 180km/hr) and be tuned differently from stock.

Are you planning to get a Nistune?

If the answer is yes then it may be possible to take out the Mines chip from your ecu and replace it with the Nistune chip (or it may be glued in too securely).

If the answer is no then ideally you would put your car on a dyno and do a run with the Mines ecu and then a stock ecu and keep the most suitable one.

Its different from stock, i emailed Mines and asked what they had done to it.

I would like to get a nistune, but i also want to be able to control all the stuff and aftermarket ecu's do that, but i am leaning towards a nistune due to the shear price, and if i give my fiance 2 options she would chose the cheaper option allowing me to get it sooner.

If i get a nistune and cant take the chip out of my mines i am screwwed, so i guess ill have a spare one ready to get chipped and put in and tuned

I have a 0v801 ECU here with the Nistune already fitted, you can have it for 320 delivered.

[Blizzerd]

well, i need a 800 now

From memory the MEC number Paul is going in about is the type of chip in the ECU. so like he said you may have trouble putting say a MEC123 chip into an ECU board that is designed/programmed to read a MEC987 chip. The reason people swap just chips around is to reflash the tune, you pull the old chip out and install a new one with a tune burnt on it. It makes sense when doing this to keep the chip types the same.

Because your looking at using the whole ecu you should be ok using either the 0V800 or 0V801. I'm certain there wasn't any changes in sensor types or wiring between the 98-99 run of ecu's (800) and the 99-on (801). also, either ecu is able to be nistuned.

I know it's a different car but still a RB Nissan, I ran a 89 ecu in my 92 R32 without an issue.

Edit: should also add that the 89 ecu had a different MEC number to the original 92 ecu and I had no issues.

hmmmmmmmm

so lost right now

Buy the nistune chipped ecu from KJB-R33. It will almost certainly work and if by some chance it doesn't you could always on sell it - its only the price of the Nistune chip anyway you could always take that out and it would be worth the price.

will ahve to wait another 2 weeks, just got paid and the missus has already dished out my funds, and! she has already paid all the bills from my car sale fund
