Thanks for that.

I want to do a spot of modyfying to the inlet manifold and will need to stick it back together when i'm done. Does anyone know what grade of ali the manifolds are made from or what grade of tig filler rod i need?

Sorry for lack of info, will be running an Eaton M90 blower on an otherwise stock 1990 1UZFE from a soarer, although it is in this.........

Thats one for and one against. Anyone else?

Why? Do tell. I was under the impression it was a common way of getting extra fuel through the injector when injector size was marginal?

At what kind of boost levels does an RRFPR become necessary? I'm only looking to run low levels 5-7psi on factory ecu and injectors to start with. Will i need an RRFPR?

Thanks for that, i couldn't see much in the way of size difference and dont suppose it operates at a much different pressure so will give it a go.

I'm looking to use a bypass valve from a mini cooper that has an M45 blower on it on an M90. I can't see a reason that it shouldnt work - have i missed something?

What length of snout is needed to clear the water bridge? Theres an eaton m90 come up at a good price but the snout length is 195mm from the outer face of the pulley to the ring of bolts that fixes the snout to the body. I've had a quick measure and it looks very close.

When i metered out the wires in the loom i used a thin sliver of steel to poke in the plugs that go on the ecu so i could put a croc clip on it. The steel opened out the connectors in the plug giving me poor connections all over the ecu. Took the yellow covers off, gently closed up the...

Its in and its running. It moved today for the first time in two years. Thanks to everyone who contributed time/knowledge and encouragement on this forum.

Found it ! We have a RUNNER !!!!!!!!!!

Have established that the ecu is ok, its been tried in a soarer and is fine. I am running a main relay. The error code 15 has cleared with the addition of a pair of good ignitors, but it still wont run. The only fault code now is 31 which is the afm. This shouldnt prevent it from starting...

I had heard the fuel ecus have a bad reputation, so its not connected yet. One thing at a time should have kept it simple! Fuel pump is off the m-rel trigger so keeps running when the ignition is on. It sounded like fuel to me too untill i put the old ( damaged ) ecu back in and it fires every...

I have one thick black/red not connected that is going to go to the fuel pump ecu. I have 12v at the +B on the diagnostic connector with the ignition on and whilst cranking. I have 12v at the fuel injectors and the ignitors also. That was a very specific question, do you have something in mind?

Thank you. I can stop worrying about that then This is totally messing with my head now, The old ECU that has no W warning light and has damage to the board from a leaking capacitor allows the engine to fire on every attempt of the key. The engine only fires on the first turn of the key and...

Whilst i am searching for my wiring error, im trying to address the fuel system issues. I can hear the fuel rushing through the fuel rail like a toilet cistern filling. This doesnt sound right at all. Can anyone confirm that you shouldnt be able to hear the fuel flowing in the rail please.

A little, but it took a while to get to them.

The fuel circulating round the fuel rail sounds like a toilet cistern filling - i'm assuming this is not right? I had a bit of a moment when i piped the fuel lines in and mistook the rail buffer for the PRV and piped it to the return. The pump ran but locked out when it got to 11 bar. Would...

Thanks. Have been over and over and over the wiring till i've gone wiring blind. I still cant find the problem. One thing that puzzles me though, The first start attempt is met with 3 or 4 seconds of running, enough to put out the charge warning light. After that, there is no attempt to...
