CamB

I reckon you need encouragement for more graphs, so... what's the cam timing doing when the pressure goes down?

Surely the rim would hit the ball joint? Or are we talking about different things?

Maybe, it does seem that way. There must be a good reason for it (rather than saying "including the brake pedal unless the brake pedal is an unmodified OEM pedal" or whatever would be sensible wording). But without knowing that reason the change to the rules is literally the dumbest thing I have seen this week. While I am posting... ... does anyone know if lengthening the chassis on a heavy vehicle is a big deal or easy to do (I see a need to lengthen frame, prop shaft, lines and wires and stuff) and easy to get approved (assuming its a fairly modest extension and a derating of GVM would actually be a good thing if needed).

I dunno who does good pricing on them but let me know if you find someone amenable to a discount because I want to buy a 5m A Loom and a B connector kit and maybe some other stuff.

I've got a similar vintage Motec 2 Group in something. I'd love to tinker with the settings (warm up enrichment to be precise) but it seems neither love nor money can turn up a cable

I think the G4 Atom had internal MAP and the G4+ has external. So if buying second-hand it might have one.

Double post

Try and pick one that is in the list in the software. Saves aggravation. I think the reason they pulled the map sensor was that not everyone wants a built in one especially when you only have 3 inputs (and the internal used one). Eg if using Alpha-N or an existing airflow meter. It won't have knock control if not listed.

Might depend on what you want as inputs - that seems to be the Atom's weakness on a 4 cylinder. It has 3 analog inputs which can typically get used up by MAP sensor, TPS and wideband. I've got a Storm that will eventually see use and I plan to use 2 more analog inputs for (1) switching between boost settings and (2) 0-5V oil pressure. This is a compromise for me, as if I had more analog inputs I would do more. It also only has 2x digital inputs, but that might be enough (eg high boost / low boost (if you have a boost control solenoid) and speed sensor). Also doesn't have "motorsport features" if that's your thing. Which is good, coz with limited inputs its hard to use them.

This is awesome. You answered so many questions I didn't even know I wanted answers to. Mind officially blown!

Hadn't seen the 14point7 product before. Good prices!

If offshore is an option I have ordered from these guys: http://www.corsa-technic.com/category.php?category_id=53 And I thought about these guys: http://www.cycleterminal.com/110-connectors.html Minimum postage a bit of a killer, but there are some sweet (and cheap) connectors there. Ok, I appear to have a connector fetish (I mean I clearly needed new connectors for my TPS, crank sensor, IAT, oil pressure sensor - pigtails couldn't possibly do).

This? Maybe go try make friends with a sparky as they are packs of 100... http://www.capitalcivic.co.nz/product_detail.php?part_no=39-56218

Thanks. Good feedback on the e85 route. Not a cheap exercise. I am definitely keen on the Fuel Pressure alarm idea. I just hadn't thought of it when I first wrote the post..: ... I also googled and I think it can only be an alarm: - using the boost control output the VEMS Round could probably be convinced to have duty cycle that related to deviation (above or below) in fuel pressure. Maybe not precise but at least enough to be able to distinguish between a little and a lot; but - link DIs are frequency only (fair enough) I will hook it up and log how often the alarm is triggered before I think about putting a safety in there. Or maybe on a timer (2 seconds of warning - invoke boost limit).

What a tale of woe... Hang in there. On one hand its scaring the crap outa me on my car and where I am heading. On the other hand, great positive reinforcement on me buying a fuel pressure sensor a couple of days ago. It was $180 plus some fabrication to come that I didn't want to spend but kept having a nagging feeling I better do it (because race car). It's still not ideal as I have a Link G4 Storm so am limited on inputs, and the fuel pressure has ended up as an auxiliary in to a VEMS Round wideband/EGT and will switch a warning light if pressure deviates drops below a set level (I would prefer the ECU cut boost/timing). Cost of sensor reflects a need to buy a differential one (ie should always show FPR spec as its differential between fuel rail pressure and intake) as in my opinion absolute fuel pressure is meaningless in an emergency, so hopefully will be easy to see any deviation. While I am at it, what's OS opinion on my last digital input. It's a BMW M10 with a turbo. Link will have usual wideband / TPS / wheel speed inputs, plus I am adding oil pressure, a rotary switch to go from not many boosts to lots of boosts (as its a stepped switch I may actually configure it for progressive boost on some clicks - sort of a rain mode), and a toggle switch to turn logging on. That leaves one digital input - options are: - start position switch (basically only useful for pre crank prime in cold start - not exactly a priority) - speed limit (useful if I ever do Targa again) - clutch switch (launch control) - dubious benefit on a circuit car. Might also allow flat shift but I don't overly value this as a feature - anti lag on (not gonna do it - bad for turbo) (edit - and don't have idle valve) - switch to E85 map (I can also use half the rotary switch for this with a virtual output, so not my preference, plus see below) - non-driven speed sensor (theoretically allows traction control - good theory, but I have a G4 not a G4+ so traction control not properly implemented) - Ethanol sensor (flex fuel). This is the obvious choice but very expensive (sensor $200+ is a down payment. Then, go through and work out if fuel system ok with E85 $unknown, probably need stronger fuel pump and bigger injectors $lots). It won't get driven much so I see this as a factor on whether E85 is a good idea. - some other idea, as long as it doesn't require any other ECU inputs or outputs as I am out of both... - (edit) like I could have the output from the VEMS gauge that triggers a warning light as an input into the Link. Basically a "something's wrong" input, although I'd want to be pretty sure it was reliable. I don't understand PWM setup well enough (and know if the Link is flexible enough) to make a PWM output that reflects fuel pressure, but I guess that would be a potential way to display actual differential fuel pressure in the Link rather than an alarm. Current preference is either start position switch (so boring) or run the wires for an ethanol sensor and worry about it later. (edit - or that fuel pressure alarm idea). Thoughts?
