    And cheap analog accelorometer I can more easily assembly with some rubber bands etc. to damp some vibration. I think hall sensors would be the right ones to measure wheel speed. Don't know yet how we are going to build that, but I think we make tooth count to fit with sensor. One idea came in my mind thinking this.. It might be possible to measure lock-up actions with hall sensor. If lock-up "claws" would work as tooths, you could see RPMs where first set is out. And when second is coming along, it will douple the "tooths" (in 2-stage lock-up). There speed is fast, but its only informative, so I don't know if it makes big difference or if its worth to choose thunder over fury with this cause. I really don't know if it is even possible to use hall sensor like this. Just crossed my mind.. :-)

    So, if I'm comparing Fury and Thunder, meaningful differences would be: -Thermocouples -> I need 4 so probably need to get EGT to can anyway -2 Lamdas -> I think need only one anyway - Sensor for g-force -> comes possibly with the dash or with the RaceCapture-device if I decide to get one. Is there any reason why I should choose Thunder over Fury? It has got more inputs and outputs, but Fury seems to have enough. Do I get more accurate info with Thunders own accelorometer? Do I get more precise ... something?

    Have been reading owners manual and playing with software for a couple of days now. Most of the questions I have found answers now and keep reading. More I read, more questions come out.. :-) Came in my mind, that if I would use Android/Tablet via Bluetooth, is it possible to use two tablets at same time? So one would be as dash and with one my mechanic could watch temperatures, pressures etc. in starting line. Off course connection for mechanics tab would be lost at some point of the track. More likely this would be just nice add/show off, but maybe it could be useful at some point.. Dash could also connected with wire if possible.

    Actually I have been thinking Thunder too, last time yesterday. :-D Difference in prices here are around 1500€ Black / 1700€ Fury / 2100 € Thunder, so if it eliminates need of Lamda CAN controller (400€ ) and would need to buy only sensor (100€ ,which I have, but still want to buy new one for this project) , difference ain't too big. If only Thunder could read 4 thermocouples instead of 2, it would surely be a winner.. But maby... And thanks for the pictures about the coils. GTR coils really seems to fit nicely and would surely be a good choice.

    Are these R35 GTR coils smart coils or CDI coils? Black Extreme can run smart coils directly, without amplifier, think? In rallycross they are using some VAG coils pretty commonly here in Europe, but I haven't got yet time to find out, which ones. Seem to work pretty well, since most have over 700 hp from relatively small engines, I think. My plan is to use E85 as a fuel, relatively low compression ratio and high boost pressure. Hopefully would see over 600 rwhp someday, even it is still a long road.. :-) There should be room enough, as we plan to put plenum / inter-cooler behind the cylinder block, so there would be some room above the cylinder head. M&W has got also 4 channel CDI (pro-14) that costs about same as 2 arc's, but would mean little less wiring..

    I have been told Busa coils would be CDI coils... How can I be sure?

    OK... So Extreme black has 2 CAN ports and I need to use one for EGT and one for lamda and one for dash? Or do I need to forget the dash? Is there anything else someone would normally need to connect to CAN in this type of system? --> ok, noticed that etc. dash 2 pro can be connected to serial port. Ignition outputs still are the same even I would use amplifier, I assume. I plan to use stock coils and amlifier like arc- 2 etc. (which , I beliieve runs 2 coils at the same time.. Havent got time to figure out that yet, but had some memory)

    Thanks! If I Want to measure exhaust temperatures with 4 thermocouples, I assume I need to use amplifier connected to CAN?

    Thanks!! I did download software, but didn't find this trim table yet. It sounds to be good enough. There are plenty of ECUs and so many features to consider and English is not my first language, so it sometimes feels little bit like running in swamp... So I thought it is better to just ask. Fuel Tech seems to be pretty easy to install, since it has most features in one device, but I am not used to go the easy way if result is better with banging head to the wall for a while.. :-) But still I would be happy to keep electrics as simple as possible. Every wire from devise to another is something that can break, and for every device I need to find a place to install. This accelometer seems fine, 3 axis is enough if directions fit, one for acceleration, one for braking and one? For knowing how hard I land after wheelie? ;-) Main thing anyway is to find out, if I have a wheel spin. Along the way I have learnt to appreciate this kind of forums, it is big deal for me. Jani

    Hi Everyone! I'm building a -09 Hayabusa for drag racing. I'm planning to use turbo and E85 for fuel. I got few possibilities to use as a ECU, one would be extreme black and would have couple of questions.. Can I get different boostmap for every gear? Can I get g-force sensor for datalogger? One direction would be enough..
