Righty then, back to this problem yet again
car is 1.8 efi zvh, chip, cam bla bla bla!!!
The problem is that when you floor it, the car will suddenly cut the ignition- almost as if its hitting the overboost, and from then on will continue to do so if you floor it.

However, if you are nice and progressive on the throttle, then its fine, and will boost as per normal....

I say back to this prob again, as it happened last year, and it turned out that i had received an xr2i ACT rather than a frst ACT, and that was causing the problem, buit this has been changed, and been good as gold until about a week ago!

Does it sound like the map sensor is fubar, so a new one would solve it?- and if thats the case how much am i looking for a 3 bar jobbie ? (as the management is OFAB).
Finally, i am right in thinking it is a straight swap, yeah????

Cheers for your help on my shonky lego like engine!

 

It sounds like your turbo pipes/ intercooler pipes are knackered & are sucking closed when floored. This happened to an ERST i had a good few years back.

 

dont just replace the map sensor rich, test it first... it takes MINUTES with a multimeter. tell you what, i'll help ya disgnose the fault if you help me adjust my coilovers later

 

boost hoses are all 1 year old samco's matey- and i really don't think standard boost will close them - ill check them though, just to be sure!, cheers!
Jim- no worries chap- pop round later!

 

Didnt realise you had Samco's on mate

 

rich its cause the engine wants ya to turn the boost up mate, its bored

if ya wanna test the map sensor i got a brand new one ya can test


oh and if ya look in the traders section theres a guy selling em for 70 quid delivered

 

My old on edid this and it was shat plugs, also did it once when the TPS had come off.

 

aj- no worries chap!
ginge- cheers, ill keep that in mind! And as for the boost, i can't turn it up if the car is jerking like a bastid can i lol! - should be quite nippy on a bar though!




Also, just been out to take the g/f to work, on the brakes, it boosts fine in second, no jerking, do it in 3rd, hit about 6 psi, and it jerks, then it will do it everytime you floor it, and it hits about 3 psi
anyone got a suggestion?
Cheers peeps!

edit as ive just seen nicks reply- cheers, ill clean up the plugs, and see if that sortes it- they are about a year old i spose!

 

check TPS is smooth... just use a multimeter on the signal wire...

 

and the signal wire is which one???
reads 0-5v don't it, or something like that? But if it was TPS, surley it would play silly buggers in first too?

 

depends rich... in 1st it doesnt have anywhere near as much load on it...

0-5 is the norm... mine's 1v - 4.5v on the 24v

wouldnt worry too much about the values, just make sure its smooth n doesnt have flat spots

TPS, CTS, ACT, MAP are all easy to test with a multimeter


ive got all the data here n i'll pop it over later... you workin 2nite?

 

nah, im at home tonight!
well, till 9.30 as i gota pick clare up! just come round matey- think Will is comming over at some point in his G60 too!

 

this happened on my mates s1 he changed ecu everything in the end it was the coil braking down might not be in your case but well worth checking

 

ill swap the ecu later on too then, see if that cures it!!!
cheers!

 

rich, i'll pop over and bring autodata so we can load it onto your PC (save me printing everything out) its got SHITLOADS of detail on the FRST

i'll bell you when i know a time, as i may even be out of work early!!!

 

looks like overboost :s

 

i have a spare 2bar off a saph if you want me to send it to you rich.

 

rolls whats the diff in the act sensor again??

you sure its not fouling the plugs or something? as you on beiges arent you??
maybe it kinda floods?

oh and autodata jim??? you going nat day? does it copy?

 

melv, do not discuss ware on this forum

email me instead

 

 

my old frst engine did this

a couple of weeks after it started doing it, it ran lean on the motorway and dropped the spark plug electrode through the piston mashing 2 valves and ruining the block and head.

when i fitted my new engine i used the exact same sensors inlet ecu etc and it did not do it but i had it set up

has your car been setup ?

if it was done by BSW maybe you should get it looked at again matey

 

it was set up by sanspeed.

hence why he only runs 6psi i mean would YOU trust sanspeed with your car?

 

i owuld get it looked at by a decent tuner asap

was the build done with the zetec chocolate pistons or did u fit forged ones ?

 

my engine melted on std boost 7psi so i would get it looked at

 

was done on 1.8 dairy milk pistons mate, it's tim Buth's old ZVH

and sanspeed are suposedly a RS Turbo specialist, so should be ok...

 

yeah, as per jim its been set-up, and it is mr Butchers old zvh!
looks like ill have a look over it with jimbo before comming to any conclusions!- im sure the data that he's got could come in handy!

 

so you dont have a licence for it?

pm sent in a min.

 

melv- tis a really useful cd chap!

 

righty then, cdhe3cked all of the sensors, and they all seem to be ok- gona sort plugs, and change ecu tommorow morning to see if that makes any difference

 

Oh FFS - picked the missus up, and it feels fine again!
gota sort this asap

 

just fit the special engine sooner

 

replace the lot with a 2.1 zetec and mad amnagement mate, that'll sort it

 

thats all very well, but its not built yet, im waiting on some special bits from the U.S- plus SEC's S8 isn't even out for the frst yet

 

at least yours is OK

we tested mine lastnite too... half the sensors on mine arent even connected to the ECU

 

yeah, but yours drives ok on wot!

 

roll get dingy to make you a new cossie loom and fit it

i so wanna see the ickle fezzy with the "plan"


but fit wider seats as "normal" sized people cant fit in em ( no im not fat, i am big boned )

 

rich, you dont need an EECIV version of secs... simply chop up the multiplug and make it fit the cossie connector

i'm sure the ECU is clever enough to understand and interpret the signals it gets from the FRST sensors

also remember rich that all the wiring wiggling etc. etc. that was done coulda helped

also TPS on your TPS i stripped off about a 1mm section of wire thats now exposed when i was using the multimeter, and i havent put any tape over it... it cant hurt to cover this up when you get a sec mate... its the brown wire closest to the front of the car

 

yeah, i know about the wire chap- cheers
Ginge, as for the seat- not a chance!- its great round corners being able to feel exactly what the car is doing

and i wana wait till the eeciv is rrealeased, as i don't wana have to chop up my loom.......................again!

 

excuses excuses

chnage the passenger seat for a wider version just for me

 

passenger is still a recaro, and will prob stay that way, as my bro is 6"9, and 18 stone, so a bucket is a no-no, when you comapre at other times, some of my mates are 8 stone, and about 5" tall - they'd get dwarfed by a bucket made for Ian!
