it does amaze me everytime i see a car set up on the rollers with aftermarket ecu's, they never seem to do anything with the ignition map like your original one, and once you map the fuel and then change the ignition the fuel map is then useless so start all over again!.
Just out of interest dont be shy to run lots of advance on part throttle, a stock rover dizzy runs 50deg on cruise.
And derek get rid of that 34deg at the topend bud, just flatline it at 28, no more power is gained but a very risk of detonation or melting something.
Cheers Rob, these are the sort of no nonsense comments i need. I will make some changes and retune on the fly and report back.Just out of interest dont be shy to run lots of advance on part throttle, a stock rover dizzy runs 50deg on cruise.

imho the best way to tune an engine is to run the car on the road at its normal operating temp, lets say 85deg, turn off all the correction factors, tune the engine as best you can to this temp, once you have this map leave it alone, from there go back out on the road at different temps and tune the correction factors to meet what you want.
noted... 
I didnt get any more tuning done on mine at the weekend. I cleaned it and did a few other jobs. I look forward to tuning it on the fly on the next trip South in it in 2 weeks. I cant believe i got nearly 29 mpg very easily in the Chim but only got 28 mpg out of my Mazda 323 on the trip back South last night.

Do you drive and then burn or let it burn as it goes ? What are the settings for auto tune ? EGO control etc . Is there anyone local ish to me who can set my laptop up ..don`t have a clue how to do it .
I am on my first baby steps when it comes to tuning and MS yet Daz. I knew my car was running too rich so addressed that first then made some changes to the ignition map and retuned the cruise fuelling again on the way home last week.The laptop was plugged into the ECU and the 3D fuelling map on show. Hit the G button to follow the map as you drive. All i did was glance at the AFR gauge as i drove at various speeds and throttle positions and hit either Q to richen or W to weaken where i thought it needed it. I only messed with the main cruise area from 1800 to about 3500 rpm and all throttle positions upto about 25%. You hit ALT and B to burn to the ECU. I also do regular Save As with a suitable name including the date so i can take a step back if i need to.
I hope i am doing the right thing and not messing it up too much yet
Neal gave me a VERY old IBM thinkpad that looks like its been thrown across the room a few times. It has very little software on it, never gets connected to the interweb and is only used for MS and the car. Connects via an old school serial cable and works a treat.
Keep up with the inane questions and techy answers people. I am taking notes.

I can't of upset that many on here, can I?
I am confused. Is your MS set to read and tune from the wideband all the time normally?
My MS isnt even connected to the wideband (or the old lambds for that matter).
I tuned mine on the fly manually then burn to the ECU..... done.
When is a good time to pop by Friday? I want to be at Mallory at drinks o'clock tho
