Phillip1993 Posted May 20, 2016 Share Posted May 20, 2016 Hi guys need some advice I now need to replace my boost control solenoid what would be a good 1 to buy with a standard map on my 1994 classic Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted May 21, 2016 Share Posted May 21, 2016 Have you tried cleaning it with some contact cleaner as they do get bunged up . The standard classic ones are fine ,do you know if your's is a 2 port or 3 port solinoid ? Cos if your's is fubar, I think I've got a spare 3 port if you're stuck . If it's not broke .....upgrade it 😊 Quote Link to comment Share on other sites More sharing options...
Phillip1993 Posted May 22, 2016 Author Share Posted May 22, 2016 Well mine is testing open line so I think the coil has gone but I wonted to put a better 1 in or do you think that is pointless thanks Phill Quote Link to comment Share on other sites More sharing options...
kayzarh Posted May 22, 2016 Share Posted May 22, 2016 I also have a complete spare boost control bracket. Sent from my HTC One_M8 using Tapatalk Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted May 22, 2016 Share Posted May 22, 2016 Well mine is testing open line so I think the coil has gone but I wonted to put a better 1 in or do you think that is pointless thanks Phill Mine ran 350hp with the standard 3 port without any issues and the only reason I'm currently running a upgraded one is because it came in the box with the apexi avcr [emoji41] I'm 90% sure I've got a spare 3 port you can have for £25 posted but they will only plug n play into a scoob that runs a 3 port in its oe spec or if its had a oe 3 port already mapped in . Otherwise the upgrade from 2 port to 3 port needs to be calibrated by a mapper to make it work [emoji6] Sent from my SM-T230 using Tapatalk Quote Link to comment Share on other sites More sharing options...
Phillip1993 Posted May 23, 2016 Author Share Posted May 23, 2016 It is a 3 port and dose anyone have the map sensor as well thanks Phill Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted May 23, 2016 Share Posted May 23, 2016 I might have a early map sensor kicking about but .... You'll have to stick a pic up of the map sensor showing the plug ,wire colours and part number . As they changed at v3 late 96 onwards and if you try to fit the later one (which is a common upgrade when getting a remap) it won't work unless you get a mapper to recalibrate it[emoji6] If it's not broke .....upgrade it 😊 Quote Link to comment Share on other sites More sharing options...

savage bulldogs Posted May 24, 2016 Share Posted May 24, 2016 Right I've found the 3 port and a v3 map sensor (so far ) are you getting a remap and want the v3 map sensor ,which is good for 1.7 bar ? Or fitting them to a standard map car , in which case you need the earlier v1 & v2 map sensor (in your pic) which maxes at 1.2 bar ? If it's not broke .....upgrade it 😊 Quote Link to comment Share on other sites More sharing options...
Phillip1993 Posted May 24, 2016 Author Share Posted May 24, 2016 Could you test the solenoid and see how many ohms it is as im not to sure if it is dead or not now and i need a v1 or a drop in replacement as im not going into to mapping yet, thanks Phill Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted May 24, 2016 Share Posted May 24, 2016 Unfortunately I haven't got a multi meter ,so can't check the ohms for you and can't find the early map sensor either . I'm in no rush to sell anything ,as I tend to hoard useful bits of scoob . I've got 2 spare 3 ports and 2 spare v3 onwards map sensors if you do end up needing one though. On the plus side I found quite a few bits I forgot I had [emoji15] while searching through my shed load of scooby scraps [emoji23] What's the issue your trying to resolve, anyways ? If it's not broke .....upgrade it 😊 Quote Link to comment Share on other sites More sharing options...
Phillip1993 Posted May 24, 2016 Author Share Posted May 24, 2016 it seems to get a bit lumpy around 4000rpm and then clears up from 5500rpm but if you have been giving it some for a couple of miles the boost pressure seems to drop off and the blow off is not so loud, now i have already changed the o2 sensor and knock sensor and it seems to of helped.

savage bulldogs Posted May 24, 2016 Share Posted May 24, 2016 Has it got any engine mods ? Are the plugs and coil packs in good nick ,as it Could be a misfire or air leak If it's not broke .....upgrade it 😊 Quote Link to comment Share on other sites More sharing options...
Phillip1993 Posted May 24, 2016 Author Share Posted May 24, 2016 no mods yet and plugs and packs r next on the list as iv only had the car for 1 month now so i don't no what they r like, iv had a look for air leaks cant seem to find any, would it be a good idea to get it smoke tested?

savage bulldogs Posted May 24, 2016 Share Posted May 24, 2016 I'd probably start with plugs and visually inspect the coil packs for cracks in the insulation and signs of "arc'ing" from coilpacks to head/cam cover . As they're prone to cracking due to the heat and age . Thought I'd ask about mods as somtimes even a cone filter can adjust the airflow enough to cause a misfire or flat spot . If it's not broke .....upgrade it 😊 Quote Link to comment Share on other sites More sharing options...
Phillip1993 Posted May 24, 2016 Author Share Posted May 24, 2016 ok will try and change them tomorrow and let you no how i got on thanks for your help again Phill Quote Link to comment Share on other sites More sharing options...
Phillip1993 Posted May 25, 2016 Author Share Posted May 25, 2016 Right changed them today drove home from work and it has got better but there was a hair line crack on 1 pack down the side would that be the problem do you think, Phill Quote Link to comment Share on other sites More sharing options...
Phillip1993 Posted May 25, 2016 Author Share Posted May 25, 2016 Just got a boost gauge and it's a only boosting at 0.5bar max Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted May 25, 2016 Share Posted May 25, 2016 It's probably not helping but I think some models of classic only run about 0.7 bar standard. Either a misfire or air leak could cause a lack of boost . Have you checked vac lines and intake tract for signs of cracking or splits ? How were the plugs any particular one blacker that the rest ? Are you getting any codes on the ecu ? If it's not broke .....upgrade it 😊 Quote Link to comment Share on other sites More sharing options...
Phillip1993 Posted May 26, 2016 Author Share Posted May 26, 2016 Ok something odd happend today driveing back from work today and the boost flue up to 1 bar and the fual cut came in it kept doing that for about 2 miles then it went back to normal at 0.5 and no matter what I did it would not go above that and then as I got close to the house it did it again So confused Quote Link to comment Share on other sites More sharing options...
Phillip1993 Posted May 26, 2016 Author Share Posted May 26, 2016 No nothing from ecu and all vac lines have been changed and I don't think there is any air leaks Quote Link to comment Share on other sites More sharing options...
