you mean 8-14 ohms empty 60-86 full?
I know where to look to find this info, obviously the 84-85 had a different gage then the 86-88 and then again in 89-90 but I am pretty damn sure the 86-90 BII in tank sender did not change...just the dash
The 89-90 tank is the one I found and I'm going to use, because it's an EFI tank, since the resistance is dictated by the sending unit in the tank, I'll see if can be changed with a resistor to bring it into spec.
The backwards resistance that you see is correct, and the tank goes to empty the resistance becomes greater, almost like and NTC (Negitive Tempature Coeffecient sensor) or thermister resistor.
As tempature rises the resistance decreaces, and so forth.
But I have to use the later BII tank cause of the EFI set up, and to be able to use the 255lph pump I have, and for the return line.
And really, I'm not all that worried about the valve cover issues, other than popping a head gasket cause of too much boost/timing (which this turbo is not effiecent above 20psi), and I'm running some eletronics that allow me to custom tailor the timing maps with out a chip (3 programs, 1 stock, and 2 modded maps)
They can be exicuted by a momentary push button switch(steering wheel mounted), or non-momentary switch (console/dash mounted) allowing me to flop between timing programs that can modded at 500 rpm increments(all of which can be over ridden pending on which switch is actuated), with a rev limiter that can cut either 1-3 cylinders witout loss in substantial power like most rev limiters, and this unit will also control 2 outputs that I can designate.
And this mearly plugs into the "SPOUT" connector of the TFI modual harness.
Funny you mention dropping the body on your rig, which was one of the considerations I had for mine to lower the CG and make it a bit more stable.
And as for removing the engine, as many times as I have done it already, pulling it is really not a big deal nor hassel, I belive once the set-up is finalized, I really won't have to worry about jerking it out any time soon, and if I do, it not that hard, plus one of these engine will run with a popped head gasket for quite a while, although you get boost/compression swap between the cylinders, it will still run under it's own power to get it back off the trails and to camp or trailer to be taken home for repairs, a trail side reapair could be made, but a bit more effort would have to go into it.
