Well......managed to get power to the MS, eventually got the main power relay to switch on and off and some lights came on for a few seconds...but no comms between MS an my PC.....seems I have to liberate the com port from a old modem I have....need help on that, no idea how to do that at all.......

But atleast I had some lights come on

A small step further along......not many more I hope

[lentec]

asuming win98 go to modems in controll panel click diagnostics tab
see what modem is using the com port in question go back to the genral tab select that modem click remove.
that will remove it!
if its another os pm me and i see what i can do!

I have XP on my home PC, I have recently upgraded to BB but still have the old internal modem plugged in, I think that is what the prob is tbh...but I am not a PC person, well technical side of anyway.

I'll send u a pm with my details, maybe I could call you later and discuss. Ant and I tried all we could, but with my lack of understanding I'm not sure I was doing the right thigs anyway!!

Thanks, Mark.

I did the RS232 cable check, crossed pins 2 & 3 and using hyperterminal I confirmed that the signal is getting through.
Then removed the chip in MS and crossed pins 12&13 to check the comms signal was getting to the chip, this was fine too.
Then I tried to get comms again, nothing
Also tried to reboot the whole thing by crossing the boot terminals, but no message was shown on the screen.
So awaiting a stim board to check all is ok, why is this such a hassle, wo well, it'll be good when it works, when......when.......soon I hope.

[lentec]

are you using a laptop or a pc?
how many com ports do you have?
did hyper term not give response?

[e30_Turbo]

Pc, Packard Bell, old machine, 701 proccesor and 256meg ram.

I have 1 com port I can see, the other that is roughly the same size is for the monitor. No spare ones other than the one.

The Hyperterm responded on the tests for the cable and the MS without the chip in it. But nothing when we tried to get comms up. Which is why we then went onto trying to boot it.

We did go through the com port config and set it up as per instructions.

I so wish I knew more about these things, feel so stupid I can't get this to work.

Thanks, Mark.

[lentec]

also i remembered having problems with there being no ignition live from the engine plug so i wired a new one direct from the key!

[lentec]

have you got a lift up panel in the front of your pc that might have a second com port there i cant remember if they had a second one or not

[e30_Turbo]

There is a panel at the front, but not sure it has a com port.

The pc is a 'i-connect' model, 3/4 size.....

The power source was my car battery, both switched and constant power were attached. All the relays fired up, which when not plugged into the MS, only the main power relay fired.
I earthed all three wires to the battery too.

[lentec]

i know the one! dosnt have one on the front
have you looked in the bios to confirm the port settings?

[e30_Turbo]

I think so, Ant talked me through the com port settings and with the tests we performed I thought we had established that the port was recieving info, but not from the MS, is that not true then?

When the MS chip was out and the pins crossed, I was able to type on the keyboard and that inturn displayed the letters on the hyperterm.

[lentec]

dont suppose you have access to another pc? so that can be eliminated!

[e30_Turbo]

Possibly, I need to get it from a mate and stick some ram up it too.

Should be able to do this, will let you know what and when.

I'll prob be online later anyway, if you can fix the 'offline' issue!!

[lentec]

Well ive just spent a few days moving the throttle body to the other side of the charger!

Now it seems to be hunting for air at idle.
perhaps the size of my pipes has somthing to do with it! and the t/b being 3' further away than its ment to be!

i might stop being tight and go buy a dump valve.
or do i just secure the pipes on so they dont come off?

[lentec]

another video!! with boost

[Turbo-Brown]

Cool!

Is that kind of "woooop"ing sound the charger being all angry or is it something else?

I've been making my new 2" diameter exhaust this weekend. Can't help thinking it's gonna be a bit loud though as it's going to have just a cross-over pipe where the old system had a sort of resonance chamber / silencer / cross-over. It's also just got one silencer which consists of a pair of perforated tubes and some wadding in a can. Hmmmm.

In other news, had a mate come over to lend a hand with the intercoolers on saturday. Looks like they can't go behind the front x-member as the radiator's well and truely in the way. This has left the option of cutting chunks out of the front valence which is what we've done. Not pretty, not stealthy, but at least they should fit!

[Ant]

Turbos will reduce exhaust noise by 10 db ish Alex, prolly be just loud enough to hear the turbo growl @ idle

I hope so anyway

[deano325t]

that sounds great lentec ..

ant`s right about the turbo .
mine doesn`t have a loud exhaust note..
wasn`t super loud before(ernst back box,, imasaf?centre section)
but the turbo absorbed most of it..

Dean.

[lentec]

that sound is the charger!!
Is that twin 2" or single?

[Turbo-Brown]

Yeah I was banking on the turbos absorbing enough noise to stop the neighbors complaining

It's a 2" twin Len, I've pretty much just copied the standard system only with bigger pipe and mandrel bends.

[lentec]

Well i hope your neighbors are more understanding then mine!
last night i had one of them screaming in the street that i was driving her mad!
the first ive heard of it!
said somthing about "if theres somthing wrong with it take it to someone to get it sorted"
clueless!!!

does anyone know a rolling road near southend??

[Turbo-Brown]

you can't beat the old 'someone gets more and more wound up and then suddenly explodes to the confusion of all others'

Mine aren't too bad generally. One's a bit deaf, the couple on the other side seemed completely oblivious to my angle-grinding for a couple of days straight last year, but did ask me to turn the stereo down.......Fair enough really!

I think Engine advantages in Witham have a RR..... I think

[lentec]

thanks mark
Dont think im feeling confident enough to drive it that far yet tho!
I phoned a place called moetts on the a127 as soon as they asked what year the car was i knew it was going noware.
So but dyno it is!!

[Turbo-Brown]

Yay, couple more pics of stuff from the last couple of weekends:

Both manifolds in place:



Most of the new 2" turbo system. Still needs a cross-overs pipe and silencer can. How loud will it be?

[Jon_Bmw]

Alex those pictures are pure brilliance, i was wondering how the hell you would have enough room for the turbos, not realising that one would be mounted up and the other one down, fantastic idea!

Where did you get the flanges for the manifold, are they t3? They look different to me.

Exhaust looks good, did you weld all the joins already or are they held together with joining pieces, if it stayed like that with no can i would reckon seriously loud, with a can still loud is my opinion.

[lentec]

Good work geez!
Heres mine! single 2.5"

Its still loud! even with the new box

[Turbo-Brown]

I had the flanges cut from 10mm thick stainless. Thought they'd be pretty difficult to warp, but after a mate welded the flange for this Mi16 Turbo a couple of weeks ago and it went severely banana shaped, I'm having second thoughts

The flanges are T25, but I think that the skyline T25's are slightly different to normal T25s so if I do ever change to the GT28R turbos, I'll have yet more work to do

Len, did you make the cans and the rest of the system? It's almost comical how bendy the system is isn't it (untill you come to make one that is)

[E327UKL]

my boss has got a xjr with 450bhp and lately the supercharger been sounding like yours! a bit like a trumpet, he took it to jaguar and they charge him Ԛ£1900 to fix it, i will find out what it was. Y? do they do it? all the supercharged cars ive had all whistle

[lentec]

Alex i didnt make the boxes! the middle one is a powerflow 2.1/4 expanded to 2.5" the back one is a cheepy tiger one!
But the exhaust is all my work!! notice the whole back half is made from straight lengh!!!
Also it was made on the car!! as in 8" off the floor!
Dont suppose youve had a go at wiring the iscv yet? not sure if a 2 pin unit has both wires to the ecu!
Or if i only use output 1 and other wire to +12v or earth.
It says in the manual all outputs are swiched earth?!?

As far as that noise, mine was doing that as the throttle was closed! thus making the s/c work HARD!!

[glenn]

turbo-brown,
that exhaust looks awesome.
mine is simular,
two 70mm tubes into one straight through back box,
i may have to put two cherry bombs into the system,,,,we'll see!!!

[Ant]

pipes are looking sweet gents , I think the single box is the way forward for now, be a shame to quieten our odd sounding hybrid 6 pots too much, cheaper without too

its easier to cut a section out to let a box in than vs versa so I'm defo going 1 box for now

Len the stock BMW icv is a stepper design, assuming the emerald supports this?, if not you'll need to switch to a jetronic type with the ecu switching the ground wire for on/off toggle

add me tou your msn again too dude, flatbars-AT-blueyonder.co.uk same to all you Fi ers, and Glenn the V8 M8

[Turbo-Brown]

Decided not to use an ICV on mine. Will adjust the idle speed carb stylie by just cracking the throttles open. The ECU should take care of idle stabilisation using the ignition after that.

Can always change it later, but for the time being I don't really fancy having to drill into each throttle tube and linking them all together.

[Ant]

upside of linking is they will self balance though Alex, OK its not the correct method but it works

ICV is still running from motronic on mine, will ditch it later this week when I finish the IC to TB charge pipes off.

been dataloging all week based on my rough basemap, have added some tweaks to it , found out the fuel injetcors I was hoping to use ran out of puff over 6K even @ simulated 5.5psi, 42 lbs hr Ford M/sport greens ordered to cure that issue.

have to say this is getting exciting now lads

[glenn]

ant,
i ran ford(bosch) light blues on my cosworth hybrid,
but found them slightly overfueling, so switched to dark greens and were ok.
good power and good mpg,(when not using right foot, which wasn't often!!)
