Installed the later model ECU just before....
Plugged it in.... connected the battery up......turn the key to on.....no problem there.....turned the key.....VROOOOM!
It works:beerclash
Drove it around for about an hour, no problems.
Throttle response is better and u can fell that extra 20bhp there too, my head gets pushed back a lot harder than before :sweat:
Now me thinks that the ECU from the manual VR4 is the same as the later models auto ECU INSERT INTO post VALUES ( i plugged the later model autos ECU into the manuals wiring loom to see if they would connect up which they did); they just started to put them into the autos at a later date. So if any of u guys could get together to do a test for me and get 2 cars that are of the same year or as close as, one manual and one auto and plug the manuals ECU into the auto. They must be the early models as well before the face lift.... duh
NICE ONE!!
Well done :thumb:
Went out again tonight, geez the car really does move with the new ECU:Eyecrazy:
I would say the ECU has gotten used to my mods by now
Now can anyone do an ECU swap to test my idea??
Hi Rhys, are we thinking that the ECUs from the pre-facelift manual cars are the same as the ECUs from later model autos? If this is the case i think that i may be able to get my hands on one and try this for us.
Tried to find the ECU but havnt got a clue as to where it is........do you have any pics/ideas so that i can see if i can get it out. ?
Cheers mate
You can get at the ECU from the left side kick panel, it the bit that meets up at the glove box. There is a post on here about how to reverse the throws of the auto's gear lever.

It will load up pics so u know how to take the parts off.
The ECU is the box on the top with the Green plugs going to it, near the fire wall under the black A/C foot pipes, can't miss it, x4 plugs.
Let me know how u get on.

There were several of us here in the UK looking to upgrade our ECU's and in fact Bonsai Boy INSERT INTO post VALUES (Graham) did. There are no issues in doing this other than the cost over here. If you are lucky enough to find a scrap one it may well set you back £250+ and a new one is nearly £1000 from Mitsy. Then someone was looking at importing them from Japan for around £350 for a new one.
So far many have stopped looking, as Graham advised us at JAE that he rolling roaded his and the extra 20bhp only really kicks in at the top end of the rev scale so unless you are racking the car everywhere in his opinion it wasn't worth the money to do it.
I have been offered the ECU quite cheap so i think that it may just be worth it for the xtra 20 at high revs. Just unsure really as to wether or not this ECU is the right one?
Did graham find any difference in 0-60 times at all?
I would think it would make a difference to 0-60 times if only slight.
For the cost if you could only get the ECU by the means stated above I'd definitetly take another route which would give performance over the entire rev range.
PM Graham INSERT INTO post VALUES (Bonsai Boy) and see what he says about actual on the road performance.
Yeah I would follow Brind's advice and PM Graham now that he has had the ECU for a few more weeks. How much you getting the ECU for Kammy and do you know the part number of it ?
Pete
BTW - more info here including part numbers: http://www.clubvr4.co.uk/forum/showt...5&pagenumber=1
Have been offered the ECU at £120. Although i need to be sure that the part number is correct? Does it have the part number on it at all, or any special marking?
The car i am taking it from is a 98 manual VR4, from what i hear this is the more powerful ECU....i may be wrong
It will have the part number on it and is it a facelift '98 ?
No it is the prefacelift model....come to think of it it has a very heavy passenger side impact, like barrys first one...its also the same colourINSERT INTO post VALUES (could it be the same car).
Am going to have another look tommorow, so if anybody needs anything let me know although the damage is V heavy! Suspension etc appears to be okay though? Will also look for the part number.
All manuals have the higher bhp ECU.
manual --> :monkey5: <-- trip
