Rapid Runner repower/refit

[Hondaz]

I don't have any sender in the boat at the moment and one to suit my existing less than 5 inch deep tank and gauge is $100 anyway by the time you add freight. Supposedly this device can also calculate consumption without senders (using injector timing pulses).

So my thinking was the $400 difference in price between a sender to get my existing gauge working and this was less than 2 tanks of gas which is about 8 hrs of conservatively driven boating.

I don't care about the NMEA stuff. Just want a semi accurate fuel gauge and that can be difficult to accomplish with a large area, shallow, under floor tank.

I've run out before in my last boat with no gauge and wasn't in a great place to have the motor stopping coming downstream into a rapid - especially with boat filled up with the wife and kids.

  You could make use of one of these Ford fuel gauges  maybe? 
Measure your tank do the math and mark the stick to match?
Tie a string on it & fasten the other end to boat! Ya don't want to litter the river now be kind boys.....

No updates for a while - work got in the way of the build.

Inspection hatch in floor under passenger set for HX.

I have all the wiring completed to here now and just have this small pile left to connect into the plastic fuse/relay box.

Pretty sure I have the tacho drive issues sorted... Needed to de-pin an unused ECU wire and load it into a different hole (not used in the Commodore) then use that to drive a pullup resistor circuit that drives the tacho in 4 cylinder mode. At least that's the theory.

Hopefully the ECU tune matches my requested setup and we should be good to go.

Having a few problems with my ECU. Sent it away to someone who has a good reputation but it wouldn't start when I got it back and was throwing all sorts of codes that should have been turned off. Then I found through sheer luck and a bit of sleuthing, that the 'tuner' had posted my tune on a forum asking for help on getting it sorted! I downloaded the tune and the software to read it - confirmed my VIN number and dug into the tune finding quite a few issues. Basic things not done etc. Anyway - it's going back to the 'tuner' to get put back to factory settings so someone else can work on it.

In the meantime getting on with the engine box. Think I'm just going to skin it with 7mm ply and some of that light marine carpet. Dunno? Maybe put some ventilation in the hinge up lid at the front behind the back seat. Or maybe talk to an upholstery guy so it doesn't look too DIY.

[Hondaz]

Going to upholster the ply engine box in with carpet. Front seat bases now wrapped with the same carpet. Still no sign of the computer so can't run the damn thing.

Oops double picture post above sorry. Meant to be this one

Coming together. Looking good!

Fantastic build. I'm Green with ENVY, 1 Question though. Is the engine cover frame rubbing against the Fuel pump? With the Vibration and Bumping environment of Jet boating. You might be wise to give it some wriggle room.....Keep at it and its bum will be wet before Christmas...

[Hondaz]

It's got a scallop in the alloy now just to give it some racing slop. The goal is to have it done before mid December but that all depends now on the guy who was supposed to be doing my computer, putting it back to factory settings, so I can take it to someone else who actually knows what they are doing to sort it.

[Jocsax]

Who was the guy doing the ecu?

[Hondaz]

Hmmm... Not sure if I should say. He has a good reputation in the jetboating fraternity which is one of the reasons I used him.

Definitely disappointed with him but monies have been refunded and as long as the ECU is not toast then I think I'll leave it at that.

It's booked in somewhere else next week (if it turns back up) so will know more then.

This is know help but..Good on ya. I?m far from a motor/ecu expert but am an experienced tradie that still gets caught out sometimes.  By the sounds of it it thee tuner is standup ie refund and prolly more annoyed than most in not being able to deliver.
