come accross this adjustable chip on ebay (D-Boos)t designed to increase power by 25HP. iv been told alot of chips designed to increase power etc. are just rubbish...

http://cgi.ebay.com.au/25HP-D-BOOST-PERFOR...1QQcmdZViewItem

has anyone had any experience with having these fitted to a vehicle?

do the dyno tests show an increase of power?

what brands are proven to be the real deal, and what have been proven to be a real rip off!

any info will be great.

cheers 4drftn

The link doesn't work, but I think I know what you're talking about. All I can say is that it's a full of shit. I haven't tried it myself, but just don't believe you can get that much power from a little cheap device.

Mate if its the chip im thinking of its not a chip but a resistor. You can get them from Dick Smith for 20c. Then you fit it to the connection of your airbox and reset ur ECU. Appartentley it adjust ur airflow and fuel ratio and ur ECU advances ur timing. Giving you the extra power. I have heard they work but i dont know about 25hp gains.

All it does is change the voltage going to the ecu from your air temperature sensor, making it think that it's a lower temperature and advance the timing as such. Very dangerous!

to the thread starter. if ur goin to listen to any advice on this topic...listen to this....

couldnt have been summed up better!

No. if u could "tune" ur ecu, then y would u bother fking around with those shitty resistors?

U want proper results, either remapped ur own ecu or get something like a PFC

    • Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
    • Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)
    • Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.
    • also possibly backed up to my filler and shat down it! 🤣
    • Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
