Hiya guys

I have an xr2 with a series 2 engine, the car has a piper285t2 cam but is still restricted to 6.2k revs;_(

I have swapd ecu,s and rotor arms with my brothers car as that revs to 7.2k but my car will still not rev past 6.2k, apparently there is a limiter on the fuel ecu?

This can be modded by changin a resistor so im told how true is this and how do i go about doing it?

Many thanks Paul.

 

This is all I know about the S2 fuel ECU.

 

ahh this is the fuel ecu did u reply to this post on the rsoc i thought this pic was the other ecu and for a series 1;_) or are the series 2 and 1 fuel ecus the same? chears Paul.

 

That is the fuel ECU from an S2.

The S1 fuel ECU doesn't have a limiter in the ECU and the pins are different so they can't just be swapped from S1 to S2.

The S1 rev limiter is adjustable and is inside the fuel pump relay (which also won't work on an S2).

I replied to a similar thread on the RSOC BBS.

 

Sound, chears Daz il swap with Marks 2n and hopefully this will be the one

 

ive gone to maplins but couldnt find the .22 microfarad capacitor any ideas where i could buy one? thanks Paul.

 

IMO dont rev yours to over 7000rpm unless you have ARP Conrod Bolts AND Anti-Pump Lifters. Even then its dodgy.

 

wont go over 6.5k and ocasionally will go up to 7k at the mo limiter kicks in at just over 6k with piper 285t2 my powerband is a bit pony how much do tuners charge for the capacitors to be fitted guna get my mums mate to fit one 2m night he said he will probably have on il bung him a £5er or £10 pritty sure tuners charge allots more for this
