Yeh same from me the momo looks right. Nice wheel.

This is the list so far There are other alerts/warnings I have on my gauges example boost gauge does low and over pressure alart. 1). Coolant level 2). Coolant block pressure 3). Fuel pressure. 3). Engine nock/det alert. 4). Exhaust gas temps. 5). Inlet air temperature high. (Potential boost leak) 6). Oil temp 7). oil pressure set to alert bellow 1bar. 8). Oil level. 9). Bonnet open 10). Gearbox oil temp. Added to list.

im designing a cmos logic IC, there not really that pricey. its there to help me fault find, as well as give me instant warning to which system is faulty. i can also make them sensitive/progressive. i can also put things in the car in there like boot or doors open. i suppose the real danger zones i can put on a buzzer to, thanks thats a good idea. ive got room for about 20 square red led lights. there are afew items that are pricey, like the nock/det alert systems.

I'm working on a warning lamp system built up of led lights to warn me (the driver) of any faults or danger levels with the engine, gearbox and fuel system, which are not monitored by the Toyota ep91 factory system Example: coolant level, coolant block pressure. Exhaust gas temp, det/nock alerts. Please feel free to join in and give me things to add to the system. I've made this dash mount to house the led indicators marked in red and yellow.

So a family member has done me a solid favour, and replaced the old cam belt with the new Kevlar race belt. Process to do it. I can't wait to be back. I'm hoping this will minimise the flex of the belt helping the crank position sensor located in the 4efe distributor driven off the camshaft be more accurate.

Looking very neat with alot of care and attention in your build. Turbo time. Keep up the great work.

Yeh same here silver.

Oh Waw fantastic work. Sounds so so nice. Well done lads what a transformation. That lad knows his stuff + mods these cars crazy quick.

How can I of posted it months ago the data is at my home in the UK, I'm in North America with work. As I've said many times. I'm so glad you have your own. Saves this conversation happening, figures crossed.

I've ordered 1 so we will find out. I'm confident it will be fine. I will swap the front pully over off the 70amp 4efe unit. Nothing to do the diameter more the fact of the length.

Looking smart as fook.

Yep it's good to be apart of a club were capable like minded people can discuss things. Gets right to the nitty gritty bits. And yep I know I'm just pointing out what I came across and to point it out. As well as ask the questions that are on my mind about people's setups and Toyota systems threw the ages. Always a pleasure to discuss these with you. I try not to read or use emotion in my posts, as honestly what's the point the only person getting wound up is the person doing this. Just on the ep91 UK 4efe system the fuel algorithm using the tps is very much suited for n/a applicat

I've just seen this now I'll get some pictures up.

It's just a process I find my self going threw as problems present them self's to me, these normally match up with other questions I have like "why is the more modern ep91 4efte control unit the same as the early gen1 4efe"?. Also pointing out the difference of the EP,804efe video and ep91 UK 4efe you have put up seeming matching the 2x systems as the same. There not. Also it's much easier to map in the earlier type system on something like a det3 low table resolution. I really do enjoy our conversations on here because my thoughts are verified most of the time, as well as giving me more

im not trying to do anything, only document what is possible. this system is the same system for both the earlier ep80 gen 1 4efe and ep82/ep91 4efte have. why is this?. this might also be interesting to lads seeking power from the N/A 4efe. or having immobilizer issues. i have recently gone back to the uk ep91 4efe ecu after intercepting the tps signal after i was not happy with the amount of fuel i was having to add. the earlier ecu is easier to map in if your a novice having a go with a simple piggyback like the det3. it also matches up to the ep80 setup in the 4ef

Gen 1 4efe 88hp ae101 ecu. Easier to work on the piggy back. Works with the bigger 4efte throttle body/position sensor (3way switch type). The starlet ep91 plugs are the same and this also has no immobiliser. All that is needed is this mod on the internal pins. I was hunting these pictures all last night to get up. This ecu fueling algorithm is the same as the 4efte in both the ep82 & ep91?. Just different values in the equation (boost). The exception is the auto ecu on all models (advanced,great but of kit) Slightly different pin configuration, sol

Rob I really don't mind you waiting. Why don't you tell us how alternators work. I was hoping for something constructive when I saw your name. Maybe next time.

she will be a 70 plate before long keep up the great work.

nice picture and motor, as well as abit of history.

no technical exercise. these questions come about as i start to look at some of the components on the 4e and its relationship with the system in general also some of the more common fitted components and the affect they are having on the system. if there is any 1 that wants to put up any info running the 4efe on the fcd/injector/fpr approach please feel free. another is people not using the air temp sensor?. are thy unplugging it driving the ecu into a fail safe mode or just hanging it in the bay to read engine bay temps? how much of an affect does this sensor have on fueling

no i was just wondering how mine was on a 1bar original map sensor, purely just going off the fact it had a blue label. as ive explained in the previous posts its been checked and found to be running a 2bar sensor off common lexus and toyotas. this is the direction of where my research is going with the 1bar map sensor and hks adjustable fcd. with me not able to test the system at present for peak voltage (fuel cut) as well as voltage raise against pressure both negative and positive, and the affects of the hks fcd on the voltage signal. i cant find much online, there is the normal

the 4efte inlet will help delay the spool up of the ct9a turbo your running also. so this should help mpg slightly. mine has not got an fcd in the system. just the stated map sensor. i was wondering on the voltage that induces fuel cut?. also why is the hks fcd adjustable does this bleed off voltage or clamp it?. if so would it be usable on the 4efe 1bar sensor. all these questions are out there.

no mine has a more modern blue labled 2bar denso map sensor from a hylux on it. i know the civic denso sensor didnt hit 5v at any point it maxed out around 4.2v at 6psi/8psi if i remember correct (thats the voltage from the map sensor into the det3) we think this is the original sensor for the d16y8 engine but he did get the car in bits with alot of the turbo parts already purchased ready to just install, it was a ongoing turbo build. i just adjusted the tables for best response on the det3 making the most and smoothest power i could. but yeh your right if the sensor tops out

yeh i get you. if the det3 map sensor does not determine load like the aem sensor does.

im going to get another simple tdo4l 4efe done for a friend as soon as i can this year on the det3. so all this will come in very handy. im also going to try and setup the output of the original map sensor to accept boost pressure like i did on the turboed civic d16y8.
