Can anyone tell me if the Techtom mdm-100 from a toyota supra will be compatible with my 1990 300zx Twin turbo? I know i will have to modify the wiring on the techtom but assides from that are all the readings the same? Thank you for any help

I have a 90 TT Targa auto Jap spec, It recently had an engine rebuild due to a knackered radiator. Cut a long story short, the engine has been done very well, but the wiring was completley butchered and am currently trying to repair all the faults!! : 1) Speedo goes hay wire, 100mph when stationary!!! Impressive but annoying!! 2) Power steering intermitant, suspect air in system 3) the most important!!!! It seems that sometime the car goes like the proverbial of a shovel the next its flat! I never know whether its going to go or not! I have replaced all the turbo and coolant hoses with piperX ones so there shouldn't be a leak! Is there a Safety boost limit that migh…

Can you help me - I need to know which wires to the speedo and tacho carries the pulse? Much appreciated. AndyGP

Is anyone else having probs with these ? The light flickers on and off on the AF gauge and the temp gauge doesnt read what the car temp gauge reads. Just wondered

Hi does anyone know where I can pick up [from the ECU] a signal that identifies which gear the autobox is currently in? I am expecting something like this for a four wire system ... Park Rev. Ntrl. O.D. Drive 2nd 1st Signal A GND GND Open Open GND GND Open Signal B Open GND GND GND GND Open Open Signal C Open Open Open GND GND GND GND Signal D GND Open GND Open GND Open GND I basically want to add a digital display of the current gear and/or a digital readout of the stick position! Any help appreciated. AndyGP

Just had a local garage fit some rear tires. Had a look at the car yesterday and they've damaged the rim on one alloy quite badly and it will need refurbishing. They said the old tyre wouldn't come off and that's why it happened. I've not yet paid for the work or picked up the car, so where do I stand? Personally I think they should have called me when the tyre wouldn't come off so I could accept the risk of the alloy being damaged or taken it somewhere else to be done....

just by that dodgy D shaped roundabout/junction seen at about 5pm, was it anyone here? yaseen

I parked next to you outside the prince of wales hotel in southport on thursday, hope you dont mind i had a good look around your Zed, tis a luvely example pal, keep it that way. Disclaimer: I have beeen the pub tonight bu ti can still typoe! Dan.

I'm sure this has been discussed on here before, and I have heard one or two opinions against fitting dump valves to Z's, but does anyone have any experience in running the HKS SSBOV dumps (or any other BOV's for that matter) on a TT? I have just fitted a z-tech ecu, which has made a marked improvement over the stock unit, and want to add a few more bits. But do dump to atmosphere valves work with the air flow meters in our cars? I have heard of the problems you can run into with unburnt fuel causing hesitation and backfiring when changing gear. But I only plan to run up to 14psi as a maximum. What do you reckon?

Hi All I am going to fit a Greddy Profec B spec 2 to my TT in a few weeks, and was just wondering if it is possible to drive an electronic boost gauge e.g. a Greddy one, from the boost controller, or one of the inputs into the controller, instead of having to plumb two boost pressure sensors into the engine bay? If this isn't possible, then is anybody else out there using a Spec 2 with the boost display? If so, what's it like to read on the move? Do you really need a gauge as well? Cheers, would also appreciate any recomendations for someone in the London area who you would trust to fit the boost controller to a Z, though I might have a go myself! Dere…

Z's Just failed its MOT on back bearing n/s forked ,o/s side not that bad but getting there ,the bloke at the MOT place said the bearings are about £130 each and £40 to fit them each.Does that sound fair or is there somewhere cheaper ?

Red Zed Asda patchway 4pm 2day?????????????????????

apart from the likley hood of failing an mot, err bothered, im feeling the need to decat. For obvious reasons i want to get rid of my cats but after speaking to ryan at ztech and reading a thread in the tuning and mods part of the FAQ, i get the impression that they are the main cause of turbo failure, and the changing of PCV valves/ seals, cant remeber which is correct, can help prevent this happening WTF is a PCV valve/ seal???? :confused: Are they expensive to change/ check??? :confused: If, and thats a BIG IF, who sells them and how much. Ive had a quote of SUMO power and they want £284 +vat+p&p. which works out at £350 i think... is this a …

OK i know the reading should be .42 volts but can someone tell me where i need to place the red and black of the volt meter to read this? Cheers

Now as you all know, I have become a Zed guru in the last month or so :rofl: , but I am now stumped on this one. My spoiler brake light works fine but the ones either side dont? Fuses are fine, bulbs are fine. Any Ideas you lot. :smash:

Looks like I am going to the auto lecky before I get a ticket, unless anyone can help. Main beam ok, dipped beam dead checked bulbs, checked fuses, all ok tried earth, no difference. weird thing is I am sure one side went off a few minutes before the other followed suit, but i was driving so I am not sure. any advice?

Who's the best supplier to go to? Need them in a hurry or I'll be catching the train on Christmas eve! :( Alternatively, anyone got a spare set I can purchase??

Is there a water bottle somewhere in the boot for the rear window washer? or did I have a dream about it or summat! :confused: just to see if I can put my mind at rest and also to see if the back washer window could have a wash. cheers

Hello all, Could someone shed some light on this for me please: On a cold start up (left over night) the Hicas light comes on and stays on until the car gets warm ???? then doesnt come on again and this is the only time it does it when the car is fully cold???? Thanks all. P.S. Baggins if your reading this mate is it ok to phone ya tomorrow as got some work to discuss ;) thanks mate.

Private plate (started TIS I think). Looked like non-original bright yellow with High level rear spoiler. Only saw briefly travelling the other direction.

what size water hoses and how much will I need to do the throttle body by-pass?

Any ideas? Just been to get in the car and put the sounds on, but there seems to be no power at all to the headunit, the power arial doesn't go up, no power to the amp... nothing. It worked fine 2 hours ago... I've checked all the fuses I can see, but no problems there? Where is the fuse for the stereo normally? I couldn't see it labelled on the fuse holder cap? Any help would be appreciated cheers

Saw a Red zed on M23 junction before gatwick north bound on Sunday at 14.00 was it any one from here 2 guys standing with the car black focus flashed but i dont think you noticed. :confused:

Just had some hoses changed on the power steering, as there was a slight leak. Now I am getting a intermittent loss of power assistance while driving, most disconcerting, OK while stationary and at very low speed. Just goes and comes back again whhile driving, not a complete loss just gets noticably heavier! Could it be air in the system? or something else? Was all ok before hoses changed!

Can anyone advise of a compatible battery for the Zed? My local places dont know what a Zed is! Cheers ED :nana2:
