Ignition Maps

Post by **Coops** » Sat Jun 25, 2011 4:35 pm

Anyone help me out here with one for a 4.6 RV8,
for some reason the ignition map on my ecu has gone screwy and not liek it should be,
I also do not have a copy of it to redo,
at 3000rpm at WOT im only getting 20 degrees i swear it was set at 28

but i think the whole table maybe suspect now,

Always keep multiple backups.

before changing a map, again always make a backup so you have an easy fallback.

I just number mine "Map Name 001" and just keep increasing every time you intend making changes. So I know exactly what the last known good map I was using is.

It wouldnt be unreasonable to have 28deg of timing at full throttle though

at 6.8k mine was only saying 26 degrees,
looks like im well down on power at present as the ignition table is well screwed

Looks reasonable. There must be tons of 4.6 megasquirt maps out there to compare to.

have trial run the car up the road seems to pull a lot stronger, have lost the bog as you pull away, (lowered the throttle enrichment).
but until the windscreen and clutch are done no more testing,
they recon upto 2 weeks until the screen is done as it is a special order

searching mate, but a few quotes i have had for another £50 can have a new one.

If the screen is in good condition, will new be any better ? plus the wait.

Either the second hand screens are dear though, or the new one a good price. £50 difference isnt bad at all though. Would prob go for the new myself if I wasnt in a hurry

its due to my screen being a rare one,
its a bronze tinted screen with green top tint.

Here's mine Tone, but it's a 3.9 I do have a 4.6 somewhere but it's not that different.

This one is JED 5.2

and this might be P.R's but I'm not sure
