auto or manual ecu

slamd ef wagon · 06-02-2006, 05:55 PM

ok i went to buy a manual ecu for my ef for the anual conversion the guy at the wrecker told me its really a waste of money all the 5 speeds weve fitted we never change the ecu and havent had a problem.

some of the things ive been told are different fuel maps and if u use the auto ecu with a manual box it goes into limphome mode

is there anyone on here using an auto acu with a manual or anyone that tried and had dramas cheers

Whts the name of the place that told you that?

People will tell you all sorts of crap. The best one I've read on here someone went to get one from a wrecker, the wrecker said ' you dun need a anual ec all you do is let da car idle for ten minuts and den it learns its a manual'

The people that tell you that you dont, I'd bet they havent actually used a manual ecu in their car to see the difference.

i use an auto ECU in my EA no worries.

It was a 3 speed though :P and they didn't have trans computer or any of that ИИИИ, so it works perfect. You don't technically need a manual ECU, but obviously it would be ideal. I would just use the auto one till you find a manual one at the right price.

I got my parts from Athol park and they told me the same thing.

It didnt go into LHM, but ran very poor (hanging rpm during gear changes, coughs and splutters). I sourced a manual ecu (took a while) and it ran 100% better.

After a six or eight manual ECU??

I had a stalling problem, when pulling up to lights,

I had chiptorque fit a chip and they loaded the Tickford Manual program with a custom tune.

No more stalling and made more power.

6, if u can help plz pm me cheers

When i originally converted my car from auto to manual, i used the auto ecu, and it idled perfect... the idle didnt hunt around, it was 100%... I then put in another manual box and the idle hunted around... i put in Rollins EB XR manual computer and it was perfect straight away...

I then sourced a chiptorque chip, and had it put in my auto computer... The computer is effectively a manual computer, with a chip...

I originally was going to buy a manual computer, but i was told it would be not much more expensive to get a chip thats tuned for an auto computer to think its a manual... (if that makes sense)

manual computers are hard to get, so it may be an option to get a chip... at least your getting 2 things done...

slamd ef wagon · 08-02-2006, 05:08 PM

hay mate what did the chip cost, that wrecker i went to the comp was $250

Grechie · 08-02-2006, 05:45 PM

i got a question i hope poeple could help me with...

if the fuel maps are different on auto and manual ecu being manual has 5 gears auto has 4, would a EDXR6 Auto ECU air and fuel ratio be up the ИИИИ in my car compared to a manual EDXR6, like stuff up, maybe not fuel correctly, or will it run fine with the xr6 fuel and air maps???

iv been told by a source that there is a way to trick the auto ecu into thinking it is a manual one, not sure how, im assuming it by bridgeing out some terminals. i am also very interested in this topic as i have just bought a full manual conversion.

RavenLS1 · 08-02-2006, 07:16 PM

i run an auto ECU in my manual with no dramas and pulling 158rwkw.

HSVETAR · 08-02-2006, 07:27 PM

so it can be done. also another question i have. the manual and auto tail shaft, are they the same length or different, cause if they r the same it will save me some money. if any one knows would be helpful

OED666 · 08-02-2006, 09:02 PM

i was lucky enough to get mine off ebay for $150...

i dont believe the fuel maps are different at all between the xr and non xr computers... i spoke to a ford electronics place about it... they said not to bother with an xr computer... its mainly kickdown speeds and that with autos...

the tailshaft is exactly the same... i am still using my auto tailshaft.

to use the auto computer you need trick the computer into thinking its in neutral...

do what i did.. auto computer with a chip... the chip will cost $600... when you think about it, its an extra $350 for a chip... not bad...

Considering XR's run at different fuel pressures to non-XR's id say there would have to be some difference in the maps.

I thought the same as well... but i spoke to EMF in brisbane when enquring about an ECU...

they are a ford electronics place... sometimes its hard to get the real answer i guess...

Grechie · 13-02-2006, 01:38 PM

im runnin now a edxr6 auto ecu, all seems fine atm

slamd ef wagon · 13-02-2006, 07:17 PM

ok cheers mate ill try my luck

Grechie · 13-02-2006, 11:13 PM

yea its running as normal as the EA manual ecu did for me

04-03-2006, 09:59 AM

Any More info on the Wiring Loom to trick the auto ECU
Every Seems to mention it But know one is saying how to do it

moody · 04-03-2006, 03:00 PM

on my cfi t5 i ran an auto ecu and it ran fine...though i had to advance the timing to tdc...ran the same as a manual 1 cept wouldnt idle properly until it was worm...oh it was the mpi auto ecu as....wasn't as smoothe thopugh and i lost bout 80-100k per tank.
