Hey guys trying to put a microtech lt12s in my 33 4door. I've got a plug and play set up but the power circuit was f**ked. So we've found a new power for the Ecu and plugged it in.

The hand controller said everything was ok and we set the tps to 0 then tryed to start it.

The starter motor was turning it over then stopping suddenly and ticking like the battery was flat. So with the jump leads hooked up to my room mates car we tryed again and it did the same thing, Then it stoped and jus ticked.

So thinking we've done damage we've out the old chipped Ecu in and it's still doing the same thing.

I'm pretty sure I've done the starter motor but I don't understand how. I'm also keen to jus see this Ecu work but so far the plug and play has given nothing but trouble

Can anyone help out please

Kk now I've discovered I can turn the engine over by hand anti clock wise then when I go back the other way it gets to a point and stops like its locked up. But yet the car was running and driving this morning

Kk jus about to put the other starter motor in. But we jus discovered with the starter motor out I couldn't turn it clock wise either but I put a breaker bar on it and pushed hard as f**k then it turned over and seems fine now. Ill try another jump and another starter and fingers crossed it works

It gets hard to wind by hand because it has compression.

I told you in the first reply to check some voltages and this would have eliminated electrical fault with the start circuit. Hard to help people when they dont listen....

Mate compression isn't that tight. U can always turn it over by hand with effort. But when your pushing hard as f**k and it don't go that's worrying.

I was getting worried as my room mates n12 did the same thing jus before it blew the Ecu.

And was kinda hoping for some advice on microtech plug and play as well.

I was told it would jus go when it pluged in but now I've got no spark and my exhaust is loaded with fuel from tryin to crank it.

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
