Loosing the dizzy is probably one of biggest benefits of an aftermarket ECU.
But I am not sure if it's worth the effort for sequential injection. We're talking of improvements behind the comma IMHO. But if you're like to fiddle around with things it's worth it

Looks like I'll be digging the lathe out then I'll PM you my email for some photos if that's ok.. Thanks
Steve, Dizzy less is something I will definitely be doing. Sequential may be out of my budget... *goes off to start searching fro more details on sequential injection*

John, I run motec and it uses a 36-1 trigger mounted on the pully. It mounts with three M6 bolts and is easy enough to mount. Triggers will have somthing suitable. If you are going to run sequential injection then you will nee a camshaft sensor also. Gustave and others on S14.net have done a lot of work on this and I think someone has some spare kits to facilitate this also. If you are going the sequentioal route then you will need to do some work on your wiring loom as the injrctors are wired in pairs as stock. Whilst your at it you might as well go for distributoless ingnition too. Oh the fun to be had. Steve |

I did get the wheel from DTA - but it is no different than anything else (plenty on ebay) just more expensive. It is mounted on the inside of the hub. The flange is reduced and the mounting ring 'turned' to fit.

Karl, I'd be very interested to see some pics of the trigger wheel/sensor mounting. With the adjustmetn in the software, I'd not thought too much about the actual positioning... but I will now. Did you use a DTA wheel? Have you mounted the wheel on the inside or outside of the pulley? Uwe, No offence taken. I'd like to think I'm capable, but I suppose I'll just have to find out. I also know a couple of people who have done a fair amount of mapping before, so I can call on them if needed. I also have another project car that will be getting a mappable ECU (ign only on a turbo mini) so it's something I have to get to grips with anyway. I also live just round the corner from 215DMX, so if this project goes ahead, I'm sure I'll drag him to the pub to discuss load sites etc...(I'm sure he'll be ever so glad to read this!
John

I have done this for my DTA engine management system. 36 -1 wheel with sensor mounted below water pump. The most difficult thing to do was to mount the wheel on the pulley - in that the first time I did it the mounting bolts (4mm) sheared after one track day. I was told that the inertia forces can do this. It is now mounted using a 10mm by 6mm steel ring that is welded to the trigger wheel and then radially secured to the crank pulley using four 6mm allen key bolts. This setup is fine. Make sure you incorporated some sort of adjustment for the accurate alignment of the sensor. You may be told that you can adjust for misalignement of the sensor in the software BUT if done correctly you wil be able to use another DTA or Emerald ECU by just plugging it in rather than resetting parameters. My engine is out at present being rebuilt so I can take pics very easily at any angle. THIS WILL NEED MAPPING BY SOMEONE TO GET THE BEST OUT OF IT and for DTA expect about �450.

MOTEC doesn't use BMW trigger wheel BTW.
I would go for EMERAD. You can't beat the price they are asking for the mapping. No offence, but are you able to map iginition? And all the other stuff? (cold enrichment, accel enrich, temp compensation blablabla) Maybe worth talking to 215DMX. He's done a lot of research for his MOTEC. |

Its a shameless plug, but there is a crank pulley on eBay right now

I'm toying with the idea of fitting aftermarket engine management to my E30 m3.
I know a lot of people go for the MAXX Alpha N, but I'd prefer to be able to map ignition too. Especially as total cost shouldn't be all that different.
I won't be able to afford Motec, so it's likley I'll be running OMEX or Emerald. I've still got a fair bit of research to do, but I'm thinking of this as a project for later in the year certainly not for the next few months.
Shortly (in the next month or so) I've got to take my engine out to do some bodywork. While the engine is out, I thought I'd fit the crank trigger wheel that I'd need to run my EMS. For any of those who are running some sort of EMS, what wheel did you use? I'm pretty sure the motec runs on the std sensors, but I don't think the ones I'm talking about do. I know most EMS will run using any of the std wheels (36-1 , 60-2 etc) but I was just tyring to see what others have done.
Who else out there is running aftermarket EMS?
Anyone got a spare crank pulley they want to sell so I can get prepared before taking the car off the road?
Cheers
John |
