Have a look on www.mkiv.com/manual/1995_electrical_manual/index.html.

Except that will give it a constant 12V whether or not the engine is running etc. Not a great idea imho! You need a relay triggered on the output from the fuel pump ECU. 9 or 12 V is enough to trigger the relay, which then switches the constant 12V to the fuel pump. At least I think that's how you do it!

Ah yes, you're right, makes sense when you think about it I suppose since it taps into the injector wires rather than cuts them.

Ah, but the point of the exta injector harness thingy is that you don't have to alter the airflow signal - you can leave it as is and add or remove injector duty cycle over whatever the ECU has decided on using the additional injector map. Or you can change the airflow signal if you want to, or do both.

Ok, this sort of makes sense. I think what they're saying is that the fuel map is basically a table of percentage adjustments to whatever the current duty cycle is. Normally one axis of this table would be the airflow meter reading. But using the add on MAP would mean that axis would now be the reading from the MAP sensor instead. So above the limit of the normal airflow meter you could have a map that added on extra percentages. So at the max of the normal airflow meter, say that the standard ECU is setting a 80% duty cycle. In your map you could then add on 10%, 15% and 20% at various MAP readings above that. Then you'd get 88%, 92% and 96% duty cycles respectively (obviously crap figures just for the sake of an example). So you basically you're just modifying the basic duty rate that the ECU has set, but you can modify it by different amounts based on the reading from a separate sensor. The difference from the SAFC is that you can increase the duty cycle above the normal max because it's modifying the signal to the injectors directly, and that you don't have to change the airflow signal that the ECU sees and mess up anything else that it uses that signal for. I think!

And in God's own colour too....

Well, as I understand it from reading the stuff on that website it can also be wired in to the injector control lines as well using one of the additional harnesses, so it would control them directly as well as/ instead of fudging the airflow signal. Could be wrong though

Yep, you have to buy it though, it's $119 on that site in the USA, or they do bundles with the various harnesses etc:- Looks like they do bundles with the Profec boost controller too, which you can use to change some of the settings. Don't really know anything about this stuff, but it looks like a decent half way house between the SAFC and proper ECUs.

The gift thing doesn't work anyway, gifts are only exempt up to £36 quid or something. However, you can get away with reducing the amount you pay. No one in customs is going to go to the trouble of trying to find the price of something if there's an invoice in there that doesn't look too wrong. Of course if a dirty great intercooler is valued at £3.50 or something they probably will! (Disclaimer - it's illegal for the company to do this of course etc etc. ) Sizes of ICs if anyone cares :- HKS Type S 23.6 x 11.9 x 2.6 = 730 cubic in. HKS Type R 23.6 x 11.9 x 3.8 = 1067 Greddy 3 row 23.6 x 11.8 x 3.9 = 1086 Blitz LM V-Spec 24.3 x 12.0 x 4.0 = 1166 Greddy 4 row 23.6 x 11.8 x 5.2 = 1448 All in inches 'cause it came from the US.

Another question, what about the power steering cooler and ad expansion tank? Do these need moving or replacing with smaller ones? Most of the other FMIC kits seem to come with smaller ones, so I guess so. If so, are these part of your kit, along with mounting brackets etc?

BTW, I checked with my insurance company the other day (A plan), and they only wanted an extra 5% for a FMIC & aftermarket front nose... Worth asking anyway.

Steve - you could try Triton Motorsports on the industrial park over by the airport, they're a jap import specialist.

For the non turbocharged F1 car? Whassat all about then? Gaz - good point, I'd forgotten about that 3%. For info, I tried to find out what exchange rate the credit card co. use, but this is far too complicated a question for the call center bod I asked! I worked it out though, the current rate is approx 177.30 I think, plus 2.75% commision, so 158000 = £915. Of course the other factor in all this is that they *ahem* accidentally get the value a bit wrong on the declaration so you pay less VAT and import duty... Ho hum, decisions decisions...

Takakaira take credit cards, so there's no transfer charges, and you get the bulk exchange rate, which is much better than the rate you'd pay if you were wiring money around. That delivery charge was door to door, including customs clearance, by air, with insurance and tracking. The HM customs site is bloody confusing, but I think intercoolers are either 3.5% or 4.5%, which makes it around £1050. Probably going to be next year before I buy one anyway, so slightly longer delivery time isn't a problem for me, and in any case if I ordered one from a supplier here they'd have to ship them from Japan anyway. I haven't decided yet, if there's not much in it I'll buy from a supplier here, but the Envy website has them at £1142. Paul - got any more details for your FMIC? Size, pressure drop, etc?

Jeez, that's some expensive pipe!

That'd have to be some hardpipe kit! CWs IC is £550 isn't it? Whereas a FMIC is ~£1000. I'm seriously thinking about buying a Blitz LM FMIC from Japan. Takakaira do them for 128,000 yen + 30,000 shipping = approx £850, plus import duty and VAT should bring it to around £1000-1050 I think. Cheaper than suppliers here. Looks like a quality bit of kit too.

I think the GReddy Emanage can with the appropriate harness, but I expect it would be pretty hard to set up. You can always get Power Enterprise 650cc injectors from somewhere like Takakaira in Japan. They're high impedance too so you don't need the resistor pack. They're still expensive though, about 80 quid each I think, plus delivery and VAT and import duty if you're unlucky...

Ah, Thorin beat me to it!

It does make strange noises sometimes, especially when the engine is cooling down, perfectly normal. And it does rattle if you shake it, it's the charcoal inside I presume.

I think he meant it's impossible to get non Toyota ones (uprated or whatever). You can get standard ones from Mr Toyota.

Yep, filter is a sod. I prefer the above method. Take the battery out, unbolt the power steering reservoir and hope you have four foot long bendy arms... Plastic bag method is definitely advisable as Scooter says.

I thought the Walbros only worked properly at 12V, so you wouldn't want to run it at 9v by reversing the mod?

Last one...

And another...
