hey all,

having a wierd prob with the auto .. not sure whats causing it, wondering if anyone else has had a similar prob

usually only happens when the car is cold, after about 5 mins of driving, and only if i have accelorated hard (usually)

the prob is it wont change out of first, will just keep revving away... one way around it is to use the "power / snow" switch to force it into 2nd gear, it will change and hold in that .. but not change up. tried using the shifter to manually change, and doesnt do a thing. then after a few mins of that it will change into 3rd and all will be fine.

any ideas ppl?

cheers

from what i was told when i had the shift kit installed they did a service at the same time. i seen ya in adelaide, i had it done @ MV auto's, they seemed pretty good so i wouldnt wanna think they didnt do something when they said they did ??

no harm in having another done tho ...

cheers for the advice

hmm... i was thinking it could be an electronic prob, but i didnt consider the ecu having any affect on it?

i guess it wouldnt hurt at all to do a reset?

does the trans have its on comp, and if so would that be "reset" if the supply is removed too? i wouldnt think the auto comp (if it has one) would learn **** all tho, so it would have nothing to reset back to.

so i explained it ok then if you had the exact same probs i guess ....lol

cheers

i got an alarm installed within first week of buying car, but cant say i noticed it until months later i think.

first would happen once in a blue moon, its progressivly happened more and more often til now when its on kinda a daily basis, perhaps every 2 - 3 days

was it exactly the same prob that i described, if so did it happen to you everytime you would drive the car? or occasionally like mine

cheers again

shannon, my problem was EXACTLY what your talking about. I disconnected my battery overnight, so it may have had an effect on the auto's computer also.

Maybe you have been driving your auto a little like a manual?, holding it in 2nd till redline? *shrugs*

anyway, try disconnect the battery overnight, if it doesnt solve your problem i would suggest a tranny flush.

Shannon:

Just wondering if you had an aftermarket BOV....

...too weak a spring on the valve can cause it to stay slightly open on partial throttle, ie mild acceleration.....and that seems to cause the auto box to stay in gear ever so often...

...easily solved by uprating the spring, or adding a washer or two to shim it out....

If you have a standard recirc BOV, and think it might be weak, borrow someone else's, or blank it off for a bit...just take it easy if you do...

Hope to help..

      WGNC34 - floor mats

      By Marek · Posted

      Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏

      Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though

      Ethanol Content Sensor - Always at 11%?

      and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.

      Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.
