My 3.9 V8 Mk3 Capri

[rob@vems.co.uk]

I wonder if there could be a setting thats crept in when the Firmware upgrade was done last year. I doubt that its hardware because the changes would be calculations to adjust the injector PW and thats all handled by the software.  If you could download your config files then it will be possible to use a diff tool against a known good config to see where the odd differences are.

latest config is this one Rob,

[dnb]

Maybe the easiest solution would be to put my TVR config on there and alter the trigger and outputs back to what they should be for the Capri.

im ready to try anything David mate,
i just want her running right so i can rest from going out and doing config dloads and datalogs every time i go out

That makes sense, we know that your one works.  Bugs are funny things as they dont behave in a way that makes them easy to catch.

for anyone following this post,
the ecu now has the ego working ;-)

[Tony C]

Dnb kindly reworked my VE table,
and i have had to change it a bit more to cure trans shut in the lower rpm range,
but think im getting good now, the ego seems pretty good to the target lambda,
what you recon Rob?.

also got sent this pic from the track where we were testing with the vems and the new squirt of 150bhp nitrous in march, not bad considering she is on stock leaf springs and we have nearly got the front wheels off the ground at launch

right hi and merry crimbo to every one,
sorry not been about, due to the car off the road had nothing really to report back on,
BUT thats all going to change  (Oh f**k i hear Rob cry ),
just getting ready to order the trigger wheel etc so i can go over to wasted spark,
im still a bit consirned regarding the retard when on gas,

we have covered this in the past, but never with a 100% outcome, so im bringing it up again as now it needs doing,
my present set up is a mallory coil and dizzy with a mallory CDI unit, (has built in retard feature )
when on gas the nitrous controller sends a neg trigger to the cdi unti at a set point which the unit then retards the ignition,

is there any way vems can be controlled the same way?
e.g if it gets a neg signal from the controller it can retard the ignitition?
i dont really want to do away with my n20 controller as it is a race version one.
rod if this is in wrong section feel free to move please,

[rob@vems.co.uk]

Tony, the newer versions of the firmware have some nice N20 controller features.
Take a look at: http://195.159.109.134/vemsuk/forum/index.php/topic,618.0.html
For a brief description of what's available.

i have just posted regarding the solenoid firing,
the only concern i have is, if the pulsoids are triggered by something else other than there controller i have no warranty against wear or engine failure due to a malfunction mate,
this the faetures of this controller: http://www.noswizard.com/product_desc.php?id=101

http://www.noswizard.com/OLD/images/pdf/max_extreme_text.html

if there is anyway the vems can accept some sort of input to retard the igntion at a set position that would be well cool, as i keep my warranty on the Nos parts then,

sorry this is the correct link to my nitrous controller,

Stick to using the NOS controller that you have, if its got a warranty then you'd be mad to start dabbling elsewhere.

The Swedish guys have stopped using coil-packs on the big power engines and use distributors and external ignition packs because they need the high ignition output and coil-packs don't provide it

If I could suggest a plan of action it would be:
1. Investigate the triggering of your CDI unit - if it can be triggered by the VEMS then:
2. Mount the 36-1 trigger wheel from Triggerwheels.co.uk - I think he does a Rover V8 mounting kit.
3. Get the fuel injection working on the 36-1 setup.
4. Get a solid mounted distributor for the rover (no mechanical or vacuum advance/retard)
5. Trigger the CDI unit from the VEMS

doh wish i posted this months ago,
as just sold my dizzy etc,
and bought coil packs :-(

also any reason why im not getting any reply notifications on the new forum setup mate?

this is my cdi unit mate:
http://www.malloryperformance.com/ProductDetails.aspx?modelNumber=685&productID=2562&majID=534&minID=5342&selection=3&minselection=1

and install manual, does this help regarding triggering?

[rob@vems.co.uk]

You'd want to lock a standard dizzy, you've still got the CDI haven't you?

I can't read the pdf because I'm on a mobile phone connection.
