So lately been mucking round vr4 standard computers,
so out of interest i thought id check the Magna ECU in computer.
because all the intermittent problems I've had since the EFI conversion :
really hard to start at times, sometimes won't at all
when stone cold revs to bout 4k till warms up
backfires through airfilter ocasionally
after warms up idle cuts out itself

thought most of these problems were cam related
but maybe not
took ECU out of car, could smell the dreaded fishy smell, before i opened it (bad sign)



as can see the caps have been leaking, and think started to eat away board, i will try clean up at work
and change the caps, but think the boards beyond repair but will see

maybe have to have another dyno run when get it sorted, and see if any improvement on power.
cos i'm thinking should run alot better when sort it out.
anyway will see what happens, but probably looking at getting another ECU would be easiest way out
spose good in away, found the heart of most of the problems i think.

[81GH]

and with caps removed can see the tracks on the board are stuffed.


so ended up getting another one, they had so many tr's at the wreckers over 10 i reckon.
but only 2 had same comp as mine, i didn't know for sure if they were all the same, they look the same inside i think
so just got the same as i had, although both had been worked on before, i wanted a virgin untouched one

so does anyone know the differences?
Mine had bosch part no. ending in 021
lot of the ones there had bosch number ending in 046
is there much differences
most were autos but think there were few manuals for memory
they also had 046

Thanks

I don't believe there was a difference in the ECU's between autos and manuals They just ground the A2 connection (Park/Neutral switch for autos) in the manual ecu's. There was a minor difference between the TR and TS ECU's, the TS needs a knock sensor.

Cheers.

today was a nice day and was sick of the cordia
so gave siggy a much needed wash and polish
and a much needed run, was running not to bad after its drive,
was misbehaving a bit this morning at first though.

she didnt come upto bad apart from the stuffed front end and gaurd
still looking for decent panels
poor siggy's been shed ridden for few months
cant wait to finish the cord and start playing with her again


and added a sticker like the one on my gh for goodluck, my gh was so lucky for so many years
don't want anymore bad luck with the GSR

[81GH]

red or black



i reckon red

hopefully the time will come again, i can start tinkering with siggy again.

Are those oil caps push in or twist on?

[81GH]

twist on, haven't checked if they leak yet, but being cheap they prob will. lol

[ISKA8]

that oil cap looks good,wonder if you could just get one with just the mitsu emblem...?

[81GH]

dunno haven't seen any on my ebay searches
maybe ask the people i got these ones from
http://cgi.ebay.com.au/ws/eBayISAPI.dll ... 1438.l2649
they are cheap copies, so they maybe able to change the emblem

a mitsi diamond would look better aye

[81GH]

put a different steering wheel on, nothing expensive
just a bit brighter and cool shape dunno if gonna keep it on sig yet

[A112H]

Too many different blues I think, maybe you could move to Sturt, lol
For anyone not in SA

[81GH]

lol ahahhaha

[81GH]

hey all been awhile since ive done anythin with sig pig. Hopefully get bak into it sometime in the new year.

First thing i need is a surge tank for fuel what do ppl recommend? Or should i just ebay it? Or does it depend on the fuel pump u have. Also dont have alot of boot space plus the battery is in there.

Does anyone have an older haltec comp they wana sell?

[TUFSIG]

plenty of room in a sig for surge tank and battery below is mine in TUFSIG



Very easy to do

[81GH]

yea forgot 2 mention theres a dual 12" sub in the boot 2. But spose thered by room on the side where the jack stuf go. Most of em seem 2 b round 2l. So shouldnt b 2 big hopefully. Im just sick of goin round corners and havn 2 bak off till the fuel stops splashing round. Which is a pain cos that used 2 b my fav thing bout sigs. Hitn corners hard hehe.

[GB_BB4C]

This is what i have in my GK, Sits where the jack used to be. Is hidden by the boot interior panel. Pumps are mounted outside. Approx 1.5 to 2lt.

[81GH]

yea think thats were got the idea from wen looked at ur pws. Do you need an extra fuel pump 4 that? Hows that galant goin?

[GB_BB4C]

yea think thats were got the idea from wen looked at ur pws. Do you need an extra fuel pump 4 that? Hows that galant goin?

Yeah, it's the same as what is in the PWS.
Need a lift pump to fill the surge tank (low pressure, high volume) one that is suited for a carby (approx $50, i use a FuelFlo brand one) bought it from

Continental Trading & Agency Pty Ltd
12 Bailey St, St Marys, SA, 5042

Then just run ya EFI pump off of the surge tank.

Which Galant... Got 5 now. 3 sedan's and 2 coupe's

[81GH]

thanks for the info. Wow i thought i had 2 many cars. Must keep u busy! Yea i meant the one u had at the hp show with the gk. Have u got 2 of them? They look rad.

[A112H]

I have a tank and facet pump I won't be using if you are interested? $80 the pair.

[81GH]

a112h could i get rough dimensons of tank to c if itl fit. If will fit fairly interested Where u located?

[A112H]

I am pretty sure it is 1.5lt tank so a little smaller than a 2lt coke bottle. Has a base plate to bolt it down and a mount for the efi pump. I will find you a pick.


I am in Paralowie but I am on holidays now so can meet you somewhere central if you are south?

[81GH]

sounds gewd can i get a pic? How old is it?

[A112H]

Thats it in the pic above but not with that pump. Just a normal facet pump to feed it.
They are both brand new. The tank has never been used and the pump was used for 3 start ups of the hardtop, comes with box and instructions.

[81GH]

oh ok sounds gewd. Sorry pic didnt load ön my fone. Il have 2 get on a computa at some stage. How long u on holis 2? I return bak on 3rd of jan. And break starts 2day. Where u reckon gewd meet point is?

[A112H]

Anytime besides Xmas suits me.
Meeting place depends on where you are I guess?

[TUFSIG]

looks like a neet setup man should go well with the GSR

[81GH]

yeah looks awesome man, very tidy. i was gonna ask if needed any special fittings or hoses,
but looks like its sorted, well at the pump end.

Yeah i'm about 50mins-1h south of Adelaide sorta off the main road to victor.

sorry to be a pain but could i get the measurements of the bottom plate?

[81GH]

Got some late XXXmas presents for sig


Haltech E6x Computer, hopefully can get it running better with the cam in it, if not can use the comp for something
else, be nice to go turbs, but that means engine gotta come out again cos i got flat top pistons
but may do that if i have to dunno.

also short shifter



Bout time i started to play with it again

[81GH]

took the stocky shifter off today





Put the Mk1 Starion Short shifter in, fits perfectly, love it, so much more fun to drive now, and easier
with the really heavy xtreme clutch love it
