    Tacho feed

    I have an Evo 2 that I have converted to coil on plug, and the tacho dont need high level signal. It will work with an aux-output setup as Tacho like most "newer" cars do. The plugin ecu should already have a tacho output taken care of. I assume you are using the plugin ecu for an Evo 1-3 vehicle?
  2. I wouldnt bother with map sensor as long it is an NA-engine. I prefer using TPS as load with ITB. If it is turbo, then use both map and tps.
  3. Hi, Anyone have a decent setup we can start with? Engine is a Mitsubishi 4G15 running a GT2860R with a 36 mm restrictor. 302 whp running on E100. Running with an oem Audi 1.8T DBW throttlebody. Antilag will be activated via a digital input. Thanks
  4. Ah great, thanks for excellent support:) btw do you never sleep?
  5. Hi, A rally car that needs 2 more analog inputs for EGT (not Can). Have 2 free, but need 2 more for 4 EGT in total... Temp3 and Temp4 are free, but suppose they cant be used as 0-5V inputs as they have pullup? Car use DBW. Can I use only one anaalog for TP Main and one analog for AP Main, and get rid of TP Sub and AP Sub and run it in setup mode as it isnt used for the road and ditch failsafe? Then I have 2 more analog inputs free:) Thanks
  6. Little update regarding the Hella SSR relay. It still gets very hot, and after a while, it wont output full voltage... I believe I must look for something else... I just wired a normal relay so SSR relay get bypassed and pump get full voltage at about 35% injector dutycycle... Have anyone tried the AC Delco/GM fan controller?
  7. Thanks for the reply, I found a 15A diode from back in the days I raced Rc-cars with brushed motors/esc, which I soldered into the circuit, and now it seems to work, at least for about 10 mins when I tested. The diode was warm, but was able to hold it. The same for the relay, warm, but able to hold it. Stable voltage output as well. I guess I must find a more suitable SSR, but have seen other people use the Hella SSR controlling fuel pump...
  8. Hi, I setup FP Speed to control my Walbro 525 lph in tank pump. I use a Hella 4RA 007 865-031 SSR relay. 1000 hz. Problem is when the car starts, it just take about 1 min, and the fuel pump starts to see lower voltage from the relay and the relay starts to gets to hot to touch... I believed there was something wrong with my fuel pump, drawing to much current, so I scoped it and it was only about 10-12A @ about 50% duty cycle... The relay is rated 18A. Should I use a different frequency and/or a flyback diode? Any idea what can cause this? Have I got a fake Hella relay? Looks legit with the Hella stamp and part#. See scope trace:

    Random RPM Spikes ATOM2

    Are you using spark plugs with resistor? If not, you should...
  10. I believe you should reduce TQ, or install stronger rods.
  11. Finally sorted. Scoped every coil, all good. Hooked wideband to right bank, and it was pig rich... Injectors flow tested, all good. Checked right hand side cat, and it was blocked... Checked left hand also, and it have started to getting blocked also... Cats removed and all good. 407 hp @ the hubs (Dynapack). Owner wouldnt rev past 6200 rpm, so I stopped there. Power was still climbing, but he had windowed a block before and wouldnt more.
  12. Thanks I did a cam angle test, and it was about 2 degrees off. Yes one of the cams behave a little odd, but when I set max target at 30 degrees, they both seems to follow target. If I set at 40 degrees, one is not always following, it max at about 30 degrees. I set target to 50, and locked the dyno at 3000 rpm, it was almost 40 degrees. The other about 48degrees, which is max.Tried 60, but stopped at 48 degrees. One cam isnt always 100%, but it shouldnt have that low power?... Turned gear shift off. I just connected the hose and took some pulls to 4000 rpm. Seems like the problem moves closer to 4000 rpm now. Only 150 hp... Car idles nice. I think I will scope every coil to see if there is some that have some issues/bad connection. I only scoped #1. Any more ideas?
  13. Hi, I just installed the ecu on a early 350Z with intake VVT only. Car is supercharged with no pressure (hose to intake is disconnected), 630 cc injectors. New coils and spark plugs gapped to 0,6mm. Power drops after 4500 rpm... See dyno chart. I used a ramp rate of 500 rpm/s. at the dyno. Afr is about 12.5-13. Both cams follows target. Log file shows steady timing. Knock disabled. I have checked with a timing light that timing is stable from low to high rpm when locked. I also scoped the coil #1 primary circuit with my 4ch Picoscope. There is about 2V power drop at the ground, but I adjusted dwell until coil was saturated as a quick fix. See scope trace. Anyone have any idea what might be the problem with the low hp? Am I missing something essential here? I dont want to apply boost before I feel the NA power is good enough... Thanks 350Z 2000 rpm - 5000 rpm.llg Obrestad 350Z.pclr
