Hi All. Having fitted the decat and cat back exhaust I am about to fit an apexi air filter but am wondering if the induction is now going to be beyond the limits of the maf and ecu resulting in lean running. If this is the case is it time to get the ecu chipped and a boost controler fitted ,I take it that will sort it out. Any advice would be gratefully received.

I think I saw you this morning - in your MG, have you still got it?? Saw it going past the Hinckley Island Hotel on the A5 at about ten past six this morning, was it you? Nice number plate by the way ;)

Right on the series 2 PTU pins it has E1 to E6 which relates to the coilpacks I guess, marked 1-6 on the series 1 PTU. The pins on the other side of the series 2 PTU has 1,2,3 G 4,5,6 and on the series 1 they are 1,2,3,4,5,6 E. I presume the G is for ground/earth which is also E on the series 1.. Hope this makes sense, can anybody confirm this is correct... :hyper: I'm relocating my PTU, but I don't have the connectors so I'm gonna make a new loom up, just want to make sure of the connections ;) cheers Jon..

You turned down black moss lane in aughton about 7:50 tonight. Anyone on here?

Hello, some of you know me and some of you dont, however those that do will know that I never usually moan about things, however I feel that it is time I did, I have noticed a couple of traders making comments on this particular post. We have a chap who has openly registered as a user on the forum in the last couple of days, openly selling parts from his car (so he says). When it is suggested that he becomes a member he says he`s going to join after he`s sold his parts....that`s a joke if ever I heard one. As an official trader on the forum I had to go through the proper channels to become one, we all pay to be traders whereas he`s just openly selling parts and hasn`t ev…

right....all these sightings ive had and yet none of them are from this forum. How can u own a zx and not be here...do theres never go wrong? :confused:

Anyone know of a good, reliable garage in or around Preston, Lancs that are familiar with Zs. I just need my headlights replacing and an airfilter fitting??? Advice appreciated

I NEED HELP!!!! why when i back off the throttle my car backfires and jerks about like a ten dollar whore, Its doing my head in :headvswal also when its cold it misses like blind darts player, and when its warm it only misses like a short sighted darts player lol, its using a lot of petrol (put £20 in and get a max of 50 miles and thats taking it easy) done a ecu check and got a 55, but it doesnt seem to boost very well now (my stock gauge is knackered). the thins that i have done so far is as follows 1: changed injector conns 2: checked all other electrical conns including dett sensor and temp sensor 3: took off and checked afm (seems ok) but if any one wants to…

i know its a common fault for the zeds to smell of petrol, which mine does. so i got the fuel line kit in the group buy from smithy, actually i got sent 2 sets for the price of one.....cheers paul ;)!!!!!!!! (cant keep it though!). The kit looks very tidy but it hasnt totally eliminated the smell, although has helped. ive had a good sniff in the engine bay and it seems to be coming from the passenger side rear of engine, near the battery. ive tightened all the hoses i can see but was wondering if theres any others ive missed? :mad: any help would be appreciated!

red z heading toward macro way i saw you at traffic lights was in mine but was behind lorry so dont think u saw me

Just wondering really! I've had an intermittent rough running problem for ages, but more recently I've noticed that the longer I run the car for before setting off, the less likely I am to have a problem. Usually now I leave it for about 90s before driving off, which is hardly warm I know, but seems to help; however my drive to work is only 15 mins through a town, and quite often when I pull up and dip the clutch at the end of my journey the engine revs up to 1500rpm. Only if I wait for about 15s does it then drop down to 600ish. Again, if I warm the car up for longer, the less it tends to happen. Wondering if anyone else has had anything similar? Mark

Is there, or is the standard way the one that involves all that lever moving- The one on AndyP site, cos it doesnt say which light flashes the codes.... :headvswal . Im assuming its the power light?? :confused: Thanks.

not sure if box is going but the gear changes dont seem to be as smooth and when i go in to park it seems to now tick over at nearly 1900rpm instead of my norm 650ish, any ideas what this prob is??? :confused:

I know the conzult is a diagnostioc program etc but is it as simple as downloading the trial one and getting a lead to plug into my laptop?? ;)

as some know ill be doing the ecu check later but reading some previous posts. I cant understand ? if it is det then it only runs certain boost ie 6.5 well my cars boost goes right round to just before the 7 mark which according to some prev threads is almost 14 psi :eek: BUT it still only gets to 60 in about 8-9 seconds so could it not be the det??? but another thing is i know its not supposed to be accurate but there is no way my car is running almost a bar of boostI think I would have felt it Im going doolally!! chris :D how do I figure out the flashes on the ecu check?? it says long flash short flash then it gives you …

In the last couple of days noticed a smell of fuel.... this morning when i got in - it was so bad that I thought it was dangerous. So I opened the bonnet and found a loose hose clamp under the plenum cover... i managed to tighten the screw with 10 turns!! Great - drove to work without being under the influence of fuel inhalation. Parked up and noticed water pouring out from under the car. If you look from the passenger side just behind the front wheel under the passenger footwell there is a hose - the water seems to be coming from there.... Any ideas what this hose connects to? Thanks

When I have been out for a blast my cooling system seems to be pressurizing, if I try to remove the cap it will shoot water every where and the two front hose are really firm, is this normal. it does not overheat or seem to be losing water though. Cheers

Are any of these any good and worth while fitting? What do they actually do?

Hi! I somehow manage to miss what direction the connecting rod is suppose to sit in the engine, IV locket in the manual, but the manual just describes the front marking of the piston, and I have CP piston with no markings. It locks like the oil hole that's upside the big end bearing is suppose to point right, but am not sure, it mite be a difference between the right and left side of the engine. the hole is in a bump just above the big end bearing on the stock conrod. anyone that know something about this? Otto

I am running out of ideas, i think my car is running in safety boost mode as it wont go above 5 psi ? , I have a code 55, so all is clear, i have reset the ecu again today but still no joy, 5psi?. I have checked the det sensor and there was nothing wrong with it, but to be on the safe side i done the resistor trick, still only 5 psi. I have disconnected the waste gate control solenoids, still no good, i have checked the engine water temp sensor and that works (fan works on/off with temp rise and fall). I made a pressure tester to blow up my engine, no leaks anywere so i'm running out of ideas as what to check next????? So has anyone got any ideas . HELP :wack:

Hello all... Just thought I would say hello as Im a new boy here! Im not gonna bore you all with the usual newbie (search is your friend) type questions! But any advise would be gratefully recieved! After talking to Ryan from Z Tech (great help) I am now on the look out for a near stock Zed, as this seems my safest bet to finding a healthy one! I am currently looking into getting myself one imported, that way hopefully I can find one with a few handling mods (maybe suspension, brakes or wheels... or all!?) & then with Ryans help, sort the tuning out in this Country! Has anyone else taken this route? Any potential pit falls, problems or things of…

i am thinking of getting a zx300tt and was wondering how good a car i would get for approx £4000 and what are they like to maintain???

thanks for telling me how to do check if my cars running in safety mode. iLL be doing it tomorrow. reading that max power write up someone said if it goes over 9 psi someone has messed with the cars boost pressure if it goes just over 9 psi its fine and if it goes under 9psi somethings wrong' wtf mine only has 7 psi in the gauge and it goes to about 6 something is deff wrong isnt it? also which wire goes to the det sensor because apparently these frazzle chris :D

hi all, just bought rear brake light for spoiler ,, mines a uk spec so doesnt have wires there for it , on the loom that is attached to the light there are two wires , one is green and red in colour.. the other is all black ,, im guessing the black one is earthed to car , and green and red is wired to positive , does any one no which postive on the brake lights i should splice this into, to get the light to come on with brakes,, cheers, paul
