  1. Hi - kinda, trying to get my head round it. So if understand the na without o2 is similar - it tries to keep an idle but apart from runs on a set map, including cruise. So yeah in a way, its pretty straightforward to change the map - hence the adjuster pot. You could run that pot inside the car potentially if you wanted to lean out or enrich I guess. Might fit the wideband to the na just to see what the fuelling looks like Currently just learning how ecu s control things.
  2. Yeah so it knows Load, but doesn't try to match a certain air fuel ratio as it doesn't know the ratio ? ie always kind of on open loop (it never adjusts to get to stoic/14.7, its just has a map that assuming all is good at the right fuel levels, but would never know that its not ?) Its that switching that buggers up some piggybacks I think, as it exaggerates to accommodate the piggyback tune.
  3. Hi, as above, might be a stupid question.... My rev2 3SGE in the MR2 has no o2 sensor or cat - and assume early Gen5s are similar (mine does not have a cat either). In this case, can i assume the ECU is not self learning as it has no air fuel feedback going into it, therefore runs on set maps based on rev, load, etc. Possibly with knock adjustment ? Only feedback is from timing, but it wont know how much it is over fueling or not ? Hence the little pot that adjusts fuelling up or down. Question being based on using piggyback ECUs to these - if not self-learning then perfect for piggybacks as the signal adjustment for fuelling will not be self learnt out of the set up ?
  4. Petrol prices :(

    tesco momentum for the 3sgte - seems to like it but yup, going up! the MR2 gets regular, the happy little na that it is
  5. Number plate choices

    Ahh man, V6 FUP would have been perfect!!
  6. Number plate choices

    well, I would avoid any that look like Fappy...... V666 RFE (number of the beast for the beast, V6 in a 6 etc) to me looks good !
  7. Selling repo'd cars? Advice required

    wasn't there one of those debt recovery bbc things which the dodgy company basically used a different company to register the cars in a lot in, so they could not use them as part payment for a CCJ. Seemed to remember they had to note down all the cars and do a search on if they were actually registered to the company, and if so they could take them.
  8. Unplugging negative on battery ?

    Your fuelling might take a bit of driving to adjust to optimum again after its removed - the 3sgte takes a while before it will drive at 14.7 afr, and the mr2 will rev very high until its settled down - but thats the only pain I find apart fro resetting the clock and stereo settings !
  9. throttle body swap now high idling

    Did you swap tps over ? Believe they need setting up again as well. how long you been running it for ? Once switch power off the mr2 runs high idle for a while before it "learns" the lower one - the idle control valve to own
  10. Club Calendar 2018 - CANCELLED

    will be sending some in but need to take them - which means fixing up the toms lip and washing the damn thing, plus finding somewhere nice!
  11. Selling a car... Test drives?

    Depends on price - when I bought my mr2 recently I got it through eBay and as far as I was concerned I was committed to buy regardless so no point in test drive !
  12. looks awesome and I think I have just been sold on white wheels for my dark blue mr2!
  13. modified bumper

    personally I would keep it all where possible - it seems to work ok merging with the line just below the headlights - the indicators look like they will be higher up than stock, so not sure if the crash bar is an issue, but might look pretty cool,
  14. Mysterious Cable Gen 6

    JDM ? Might be the seat belt sensor plug ?
  15. Help. How much to fix

    As above - what actually is it , exhaust ?
