Hybrid_From_Hell Posted February 24, 2013 Share Posted February 24, 2013 Hose is defo wrong as bowie says Hose(s) go From Drivers side front (Flame trap) to T piece small to trumpet, and large to Plenum The 2 Wire PWM Bosch Unit is powered close, so the settings are wrong something like this if not 25% then its not powered close ON PWM 1 change 70 to 60 and 78 to 72 as well while your at it !

Bowie69 Posted February 24, 2013 Share Posted February 24, 2013 Oh, and don't use any old T-piece either, it has a specific sized restrictor in it.... otherwise you suck far too much crankcase gas into the engine. Quote Link to comment Share on other sites More sharing options...
mikec Posted February 27, 2013 Author Share Posted February 27, 2013 This is just about breaking me! Had three days off work to try and get it running, but I'm still having issues. It seems to run ok, idles a bit lumpy but ill live with that but after ten minutes of idling the car temp guage is going into the red, ms shows 171 degrees or so. Not sure wether its a fuel/timing issue or what, rads getting hot so I think the airlock issue isn't the problem. Bought tunerstudio, can't get that to connect to ecu, tried manually etc. Can anyone point me to a simple (idiots guide!) to how to use autotune?

Quagmire Posted February 27, 2013 Share Posted February 27, 2013 If megatune has been working lets stick with that for now and not introduce any other elements to the equation for the time being. I wouldn't auto tune your idle - I set mine manually and let auto tune do the rest of the table. I just tweak the group of cells around idle up or down to the point that is peak rpm/lowest map. This means that my AFR is generally richer at idle than I would like, seems anywhere between 13.5 and 14 suits my 3.5 best. I'm not sure how MS itself would cause the hot running unless running v lean or spark is very retarded. Has to be an airlock or plumbing problem. Got anymore shots of your engine bay overall so peeps can check? Don't give up - it'll be worth it in the end. Quote Link to comment Share on other sites More sharing options...

Hybrid_From_Hell Posted February 27, 2013 Share Posted February 27, 2013 171 F or 171 C ? 171F is only 78 C 171 C = blown up before than ! Nige Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted February 27, 2013 Share Posted February 27, 2013 Mike I have said this before, your looking for hugely complex solutions to problems when they are simple ie all 8 leads wired wrong = starting prob PWM - you must have changed the settings as I never use the one yours was set up Hunting issue etc etc - peeps said "Air leaks" inc me waaaay back Its not overheating at 171F You don't need TS, you need to reload probably the standard MSQ I gave you in case you have altered other settings, then Calibarte the TPS Set the tickover with the PWM BLOCKED OFF, then set the tickover on the Spark Table, then check timing is spot on and trim if required, and also ensure you have the air pipes fitted properly betweenthe flame trap trumpet and plenum with the proper restrictor, and then and only then then go for a drive with Megatune and datalog it noting any issues etc before you go and if you wnat send me the XLS file and I'll do the changes for you and email it back I can send you setailed instaructions as to how to change F to C on megatune, but it is deep in the software and is not a simple tweak Nige Nige Quote Link to comment Share on other sites More sharing options...
mikec Posted February 27, 2013 Author Share Posted February 27, 2013 Ok some pics of the engine bay 171 f, but its slightly disconcerting when the dash temp guage is showing in the red! Was working fine before though its had a new sender. The one problem I've found regarding the cooling is the top rad hose has a bend in it, which peaks higher than the rad, hopefully sorting that today. Had to bodge the rocker breather for the time being too. Nige not sure what happened with the original pwm settings, but I didn't change anything, at least not on purpose Anyway, I've reloaded the file you sent me this morn and its how it should be so honestly don't know what happened there. Set the tickover with the PWM BLOCKED OFF, then set the tickover on the Spark Table This is where the problem starts, how exactly do you set it on the spark table? I know I'm probably being extremely thick about this Thanks for the advice guys much appreciated Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted February 27, 2013 Share Posted February 27, 2013 MS can't fix mechanical or electrical problems - and from what I've read your vehicle has had quite a few, from crumbling earth straps to incomplete plumbing, to (by the sound of it) dodgy temperature sensors. So, you need to get the car straight first, then get the basics set in MS (trim angle for ignition timing, which hopefully you know by now, and the rest as per Nige's defaults / advice), and THEN see what happens.

mikec Posted February 27, 2013 Author Share Posted February 27, 2013 Ok thanks to Gordon, for coming round for a second opinion, sorted the overheating I think, hopefully a dodgy viscous fan, sticks at 81c now. Idling not too bad, but it has a bit of an issue on pick up from idle, I've done a bit of a vid and a data log, but just wondering what thoughts were on this...

Quagmire Posted February 27, 2013 Share Posted February 27, 2013 Can't get the vid on my phone, but if its a stumble/ hesitation when you poke the throttle its probably accel enrichment settings. You tune these once you have your ve table dialled in. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted February 27, 2013 Share Posted February 27, 2013 Yup, sounds like it, AE settings, but DON'T TOUCH UNTIL YOU HAVE VE TABLE TUNED. Quote Link to comment Share on other sites More sharing options...
zim Posted February 27, 2013 Share Posted February 27, 2013 I think the initial problem was the overheating. We changed megatune to celcius so we could watch it (i don't know farenheit scale!), it was warming up and getting too warm ! i.e. 95 C idling and then switch it off. Glad you've got that sorted now. Next on the list i think is a cowling of sorts to enclose the new fan you've put on. They make a big difference. I'll be honest and say that the engine bay is nice and neat Wiring / plumbing looks ok. Definately no air locks in the system. Also didn't see any air leaks. If the cooling is good and she's got an mot you're a few steps closer to having it running 100% Gordon Quote Link to comment Share on other sites More sharing options...
mikec Posted February 27, 2013 Author Share Posted February 27, 2013 Thanks again Gordon. Yep once it's mot'd ill be able to spend more time getting things a bit tidier etc, Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted February 27, 2013 Share Posted February 27, 2013 Er yeah A phone call asking how you change f to c whilst me driving in a city centre was "fun" Even sadder I could visualise how to do of N Quote Link to comment Share on other sites More sharing options...

mikec Posted February 28, 2013 Author Share Posted February 28, 2013 Mot done Is I can get back to getting it all sorted, probably sort the idle out again tomos, then try and sort the problem just above idle as it makes it quite hard to drive, almost stalls before revving up!

Hybrid_From_Hell Posted February 28, 2013 Share Posted February 28, 2013 Do me a f datalog I will look and sort for you for free If you don't know how ask and ill do a ladybird book version of how Quote Link to comment Share on other sites More sharing options...
mikec Posted February 28, 2013 Author Share Posted February 28, 2013 What's an f datalog? I've got as far as doing a datalog, and getting it onto megatune, wich then changes what it wants, I'd rather do it myself but need a pointer in the right direction Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted March 1, 2013 Share Posted March 1, 2013 If you are happy using the software, try Tunerstudio, much superior to MT + MLV imho, yes it cost a few pounds, but you will save that time by being able to do real time tuning rather than faffing about saving logs, loading logs, analyse, and then re-upload new table etc. Tunerstudio is written by the same guy that did MLV, so it is very good.

Hybrid_From_Hell Posted March 1, 2013 Share Posted March 1, 2013 ^^ Except I think it would be a sound idea to actually look through the code outputs within a XLS datalog and make sure there is nothing fundementally showing up as being wrong, , and everything that should be working is, and in the right ranges etc. before Mike starts tuning and covers up a basic fault(s) etc further. TS woun't sort out build errors Nige Quote Link to comment Share on other sites More sharing options...
mikec Posted March 1, 2013 Author Share Posted March 1, 2013 Well I'd like to be able to use both anyway, plus ts wouldn't pick up the ms the other day, wouldn't manually connect either. Ok so if I do a drive of 20 minutes? And data log it will that be enough or does it need a longer/shorter run? Cheers mike Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted March 1, 2013 Share Posted March 1, 2013 5 mins drive when WARM (over 72 Degrees) will be fine Email me the XLS file that is created, when you start logging switch it to save file on desktop otherwide you'll never find it (don't ask me how I know this from my early days of MS ) n Quote Link to comment Share on other sites More sharing options...
