update: ive got the im240 test on next wednesday at botany.

my plan is to fill up half tank of 98 and half of e85 then tune it over the weekend. the reason im doing that is i dont want to have to do any heavy tuning before the test as its a pain in the ass to tune timing on the street.

im going to disconnect my actuator too so i dont hit boost during the test. that should get me a pass as they only want to see that your CO is under 8g... THC, NOX and CO2 dont matter.

Disconnect the actuator? So it won't open up, or remove the actuator arm and wire the flap open?

Hey man. I'm the guy who's been talking to you and waiting for the money to buy the car. If this passes, will I have any trouble in the future if I don't change any gear?

hey mate, i sent you a PM with some notes.

UPDATE: car is now running on e70/85. Caltex advertise it as having between 70-85% ethanol.

a few things ive noticed is it smells a bit like vinegar/vegetable oil. i want to eat it.

other than that i'll be tuning cruise and light to moderate boost before i take it in tomorrow to see if it passes. i havent advanced timing at all, i will do this when im a bit more confident and have done enough research to be able to do it on the street without passing the speed limits!

it also feels like it picks up a bit better, feels smooth. unfortunately it wont be a full-time thing. its purely for EPA purposes.

thanks dude. got it. My buyer is just waiting for his money so I can have my money. Sorry to keep you waiting.

ok i just did the emissions test. looks like the only issue is NOx. the limit is 1.93 and i got a 2.56... i think ill richen up the tune a LITTLE bit as my CO is within limits of around 0.7 then replace the cat and try again.

what a relief.

little update. NOx can be tuned out by reducing combustion temps. retarding timing helps this. a new cat wont necessarily help (i didnt replace it).

ive richened up the map a little and im going to retard timing by 5 degrees.

im going in tomorrow so i'll let you guys know if i pass.

    • Here's one I help build and tuned a decade ago, Garrett  GTX3071R Gen 1, T3 twin scroll 0.83 rear housing. Went from larger 272 cams down to smaller Tomei Poncams to help with the low end. S13 non VCT motor. Car was purpose built for the track, hence low down was the focus. Note the actual dyno chart shows lower boost, however the EBC and boost gauge showed 1.9Bar (Ignore the torque, I was young and didn't know how to set derived torque)  
    • I’m doing some side developments on SR20det S13 engines, its one my hobby cars used it to compare flow capacity of some smaller size wheels. SR20det is one of another JDM legendary engines I'm sure there are plenty of SR enthusiasts on this forum, I will share results some common turbo configurations here. a quick run down of what the car is: Wide body 180sx Type X with black top engine (blue). It has: Stock bottom end Haltech 1500 ECU 5-0 motorsports trigger kit Kelford SR20DET Beehive Spring with Titanium Retainers Kelford Cams SR20DET S13 188-B 268/272 Cams G25-660 Turbocharger in T2 .64 rear housing internally gated ARP Head studs MLS head gasket 1000CC ID injectors Walbro 450L Fuel pump Front mount cooler kit JJR’s 3 inches turbo back exhaust (its too short for the 180sx it had to be extended) Pump 98 fuel Hub Dyno tune So far made 270rwkws at 22psi full boost by 4500RPM. Engine is very knock limited hence a pretty bad looking top end. From previous experiences it seems like SR20dets are happier with bigger size turbine, some thing like a GT30 would make way better top end, but on same time response is lost. It won't be a problem with S15 VCT engines. I'll be testing alternative turbine housing, turbine wheel and possibly dump pipe options for extra flow to resolve the problem and of course E85 would resolve all the issues.            
    • Awesome writeup and details. Thanks for sharing the story so far. I can relate to parts of it with my previous car and some of the issues I had to deal with.
    • Wow the colour matched hard top completely transforms the car. Are there any nice front lip options for the car or is that off the table?
    • Generally yes but for some reason I've been ruthless this time around!  I might even need to do another tip run after the way I've finally been able to hit the delete button on shit I've stepped over, stepped around and tripped over for the past 10 years!
