FAO any mappers out there
had api build a sti spec engine for my98 uk
until i can get the money together to map it properly i bought a 1s ecu from an sti followed the wire swapping instructions ( swap the cam and crank sensor wires (B136 pin 8 and pin 10, red and white wires) and also move the fuel pump relay wire from B137 pin 17 to pin 7 (IIRC green wire).) car starts and runs fine but on boost its stuttering (boost only set to 0.7bar) all the way up the revs any ideas what the cause of this is and how to rectify this till i can get mapped cheers in advance willie :thumb: |

Get it mapped asap, drive it off boost if you have to drive it, will be a lot cheaper in the long run if anything goes wrong would be my advice, good luck, Gaz.

1S ecu comes from a 97 WRX, not an STi. The STi ecu should be 6S for a 1997 car or 75 for a 1998 car.
Whichever ECU you run, you need to make sure you have the turbo, MAF and injectors that match the spec of the ECU (i.e. that match the car the ECU came from). |
cheers guys will remove it tonight and not drive it till i can get it mapped
|
:eek: fcuk me!!!!! someone who actually listens to advice.

you can still drive it mate when its back to standard, just don't drive with the mods you have fitted. |
yeah what i ment is no driving on boost goin to arrange to have a simtek fitted and mapped by andy f
|
bigsinky aint that what advice is for so u listen to it
dont wanna **** ma car after the money i just spent building it :) |
I think he was referring to the fact that a lot of 'stalwarts' on here give good safety advice to relative newcomers.... Only for it to, more often than not, fall on deaf ears. :brickwall
But not in your case willie... So congratulate yourself lol ;) :) |
car now has simtek fitted and been mapped by andy forrest :)

Wise move by the OP ... I've heard of people "accidently" hitting boost in un-mapped cars which have then gone BOOM!

Which brand of pistons? Properly forged jobs? Which rods? |
unsure m8 would need to check with david at api
|
They'll be Supertech forged pistons and NEW Sti 9 rods. We are the official UK Supertech dealers now.
Well done Willie got you there in the end. Good Luck David |
Nice spec motor then. ;)

500 would be a stretch on those rods 450 / 460 would be OK, I am happy at that.
I bet you've got a good tan Willie, sitting about on those roofs all day long ........ |
