what replacement ecus for the rb25det don't use the afm. i have heard of some people talking about ecus that use a map sensor.

i am trying to twin turbo my rb25det. i am going this way as i already have 2 good rb20det turbos sitting at home. if i went for a large single i would have to change the ecu anyway. so i figured running the twin rb20dets which i already have would save me the $1000 or so i would have to pay for the large single.

can any body help me with any ideas on this matter.

thank you

microtech, autronic, do a search.....and you figure you can save money on a big single....you still have to get custom manifold made up for twin turbos custom exhaust etc etc......why dont you get a high flowed rb25det turbo.....theres the cost of your custom manifold and exhausts and all the associated crap that goes with a custom setup.....sell the two turbos you have make some money there

Mate all the ecus these days tune the same

You are better off with either

Haltech E11 Plug N play

MicroTech LT12 Plug n Play

Wolf Plug N play

Hydra Plug N play

I'm curious about this hydra its apparently doing ETC and vairable cam timing isn't it?? Have heard they are working on a plug in for the EVO 9.

Thank you everyone for your help in this matter. MR331307 on the bottom of your reply it says about a 591hp r33. Is this your vehicle and if so what have you done to the engine to obatin this kind of power as it is the target power area that I'm tring to get too. About 600hp out of a rb25det in a s13 silvia should make for a very fun car.

Once again thanks everyone.

motec is basically a racing use ECU. it has many many features that an average bog stock skyline or even high powered skyline wouldn't use. it is simply not cost effective for a customer to use, given they can go for $1000 ecu and get 90% of the features they need. some of the features include

2 lambda sensor input

drive by wire control

rev limit per gear

down shift rpm matching for gearbox

3d map tables

choice of firing for upto 8 drivers

temperatre input/correction for air temp, oil temp, water temp

8 aux outputs for gate control, idle up, warning lights

porgrammable inputs (speed control for pits ie: lock speed to 50km/h)

full logging

basically rally cars and v8 supercars run motec as it has the features they need and use. gear logging for each gear and so on.

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
