VPC used to be on larry a's site... http://209.85.165.104/search?q=cache:UW1zcYtjhPcJ:oldschool.supracentral.com/htm/vpc.htm+vpc+instructions&hl=en&ct=clnk&cd=1& i couldn't find either of the other two on google...but, for $10 a pop, we should pick 'em up and scan 'em in....i'd split it with you.

eh. if it's from haynes, i can't imagine there's any real decent info in there....then again, it's probably just a conglomerate of other people's info.

the original location is OK....i just worry about it getting smacked by the engine as it wags around....especially in an '89+ car.

there are a few places i've used the "fancy" hose clamps- the ones that look like a true fitting, but have a hose clamp inside....

the open loop transition occurs around 75% throttle, so that's a good starting point...

chances are after 20 yrs or so the bulb has burned out....or they didn't offer it in europe. jeff should be able to tell you if they did...

build date?

eh, i guess i can't explain what i mean, forget about it. THA is the ECU's air temp sensor input. the idea with the MAFT pro install is to have the MAFT pro output a constant voltage to THA to keep the ECU happy. the MAFT pro takes intake temp into account in it's speed density calculation...

perhaps you missed the "+ feed"....or perhaps i should have called it something better. you'll need to wire it to an ACC ine AND a B+ @ the ECU....basically separate the two by a diode to prevent the B+ from charging the ACC....then pause for a second @ the ACC position when starting, giving the...

no such ability with toyotas....AFAIK.

that would be it!

assuming that's their AFPR kit (link doesn't work...), yes.

really? interesting....

what sort of AFR numbers are you seeing @ WOT? if it's real rich, i suggest pulling the J tube on the fuel return and drilling it out and seeing if that helps.... i recommend an aeromotive AFPR and then have someone make you up some real SS/lines and fittings. beware that most industrial SS...

modifying a car isn't about just buying parts- it's about understanding what each part does and how they work together. if you don't have an understanding of something you have 2 options: 1. take the time to do the research/reading yourself to gain understanding 2. pay someone who has the...

need? maybe. if $$ is a concern, simply hit up your local auto parts store and rent a fuel pressure test kit. if not, you'll want to remove the stock FPR and return line and replace it. there isn't a direct fit option, though there are several kits out there. i recommend staying away from...

using a walbro w/the stock fuel press regulator and stock fuel lines has been known to cause extremely high pressures (too much restriction in the stock system for the flow of the walbro). look into getting an AFPR w/gauge or renting a fuel press test kit....that may be your problem. to start...

EDIT: i am an idiot. you need to turn AFR tracking off- both WOT and part throttle. to tune low and mid throttle, simply add corrections to the low and mid tables...monitoring Vf for changes. what's your base fuel press?

you'll never find any PnP or fields type harness for the <'88 cars. your best bet is to source a FCON or VPC harness and make your own...
