yea but that was the chip that came with the kit, but to my knowledge the guy i bought the kit from used the giac chip and not the zengineering one , will a chip for a dizzy motor be different to one with a coilpack?
-
oh well that,ll be that then i don,t know why its putting out 8.5 psi as it should only be 6 psi i take it the fuelling is controlled by the map then and z engineering have got it wrong? i have a giac chip as well that was supposedly for a car with a dizzy but that was the one the guy ran in his corrado i wonder if that would be better , i suppose the only way to tell uis by having another power run done and thats another £85
-
so going to a adjustablr fpr isnt going to cure it then? and going to stealth isnt an option i,m afraid as i live in central scotland
-
so why does it need more fuel then , your gonna have to school me i,m afraid its been all big carbs and cams for me uptil now LOL i can,t get my head round the fact that its running lean but if i do introduce more fuel it will make less power, i take it its got something to do with the timing or has it? would an iffy fpr cause my probs cos it wasnt a new one that was fitted it was the one that was already in the car as its early obd1 and they have a 4 bar reg in them already, or am i missing something and i should have changed that as well
-
thats all well and good but i ain,t got the money, i,d try and get it if some of the tuners down south were nearer but tbh i,m not sure about the local guys cos he admitted he,d never done a charged vr before, what i don,t understand about the dropoff is thats when its getting richer and the power dips should it not go up when it richens up rather than down ? tbh i,m not looking for more power just for what i,ve got to be safe and not melt anything i,m getting conflicting opinions on how safe it is now some people reckon its ok but i just don,t know HELP
-
another thing i don,t understand is when it does richen up at 5500 the power and torque dip down, why is that should it not go up if its getting more fuel ? then when it starts to lean out above 5500 it picks up and goes again, i might add this is not noticable when driving it, sorry to ask so many questions but i have to bow down to the greater knowledge of you guys and the only way to learn is to ask LOL also i,ve just checked the chart and the printout says the charger was putting out 8.5psi rather than the 6psi it should have would that make a difference?
-
so what do you reckon looking at the graph? its running lean low end and top end and i need it mapped to sort it out? i just find it hard to believe that z engineering would sell a kit that runs close to melting pistons afterall they werent cheap kits,could the fact that i,ve moved the maf before the charger be a factor in this?
-
its stage one ,would an adjustable fpr sortbthis out tbh i can,t afford spending another 530 quid on it at the moment, the guy said he had the same problem with a 20v turbo and fitting a better pump sorted it
-
yep zr2 charger, what i really want to know is do i spend another £550 to sort it or is it going to be ok ?it runs fine but the dyno guys got me worried telling me its too lean but i reckon he was just trying to get more cash from me
-
its standard injectors , 4 bar reg and i think its a vr pump but i,d have to check that because i didnt do the conversion
-
went to the rolling road this morning and got a power run done the graphs are below, anyway the guy says the car was making good power but was running lean at the low end and at the top ,it was marginal but says it could be fixed for £500 plus vat ! now i,m not sure if this is just a scare tacktic to get more cash from me so does anybody know how i can get the fuelling up and do the graphs look like its running lean ? i,m not sure so any help gratefully recieved

i,ve got an oil pressure gauge to fit but i,m unsure where the sender goes, theres 3 places on the oil filter housing so which one does it go into?
-
i,ve fitted a 4 bar pressure reg ,i,ll wait and see what the dyno shows up
-
yea but it might be the fuelling thatsthe problem or the timing and the dyno will show that up, i,m worried it might be running lean so i pulled a plug and it seemed not too bad i,ve ordered a a/f gauge off the bay cos none of the suppliers around here has one

its been going sweet and its booked on the dyno tuesday morning i just wanted to know the cause of it dropping the power at those revs, i suppose the dyno will tell me everything i need to know

i was hoofing my motor along today with a wrx at the back of me it pulled to the redline in 2nd 3rd but when it hit 5500rpm in 4th it just died, it still goes ok i just wondered what could cause that to happen
-
my vr is now supercharged and i want to know what are the best gauges to have, i,ve already got the boost gauge and i think the second choice is oil pressure , but what about the 3rd choice , are af gauges any use ,or what would you guys that are running chargers pick?
-
when i,m driving normally say 60mph in top its showing 15 hg is that normal? it only goes up past the zero and into boost when i floor it , forgive all the questions but i,m paranoid about it blowing up!
-
right guys some advice please, i,ve moved my maf , ditched the isv and cleaned the maf again, its running sweet now almost no noticable stuttering pulls well and the boost gauge says its boosting to the proper 6psi, my only concern is off throttle the gauge goes to 30hg is this ok or can i do something to relieve this pressure also could the fact that my charger was soaking the maf with oil be due to the fact i put too much in it like i said previously there seems to be zero movement on the impeller shaft, i,m new to superchargers so i,m a bit worried so any advice is appreciated thanks
-
i,ve a new problem now, i read on vortex that you can do away with the idle valve and just turn the tickover up with the screw on the throttle body ,well i did that and its now ideling nice but it won,t go very well so when i got it home and pulled the maf it was caked in oil again! this time it looks like charger oil , i think i may have overfilled the resovoir but could it be a seal thats gone? theres no play in the impeller shaft, anyway i,ve spent all night moving the maf before the charger, i,ve just got the maf plug to extend and hopefully that will be it
-
i,ve jus t tried it and now its idleing up and down and blowing blueish smoke out the back it is driving on part throttle better though
-
latest update, my maf is an early one which surprise surprise is the dear one £230, anyway i came home to take it out to show a local motor factors it and found the inside of it to be soaked in oil, now this is not good so its sitting in petrol just now getting cleaned, but my problem is the breather pipe from the rocker cover goes to the charger inlet and this must be whats causing the problem so can i just put the pipe into a catch tank and block off the inlet on the charger , i take it its just to get rid of excess fumes or does it in some way drive the charger?
-
thanks thats what i wanted to hear , i hope your right cos its doing my head in!
