No, checked that. Had the battery disconnected while working on the car... I also don't hear a hum in the trunk... I just ... Just changed the fuel pump around 7-8 years ago, with a Bosch. No hum is a problem. I think my car may want another fuel pump I was looking at... I'm going to meter the relay and pump.

Hi John, missed a lot of discussion on this. Kept up with you on FB though. Thought I'd clarify some info on your ECU tune. John has a 2 way ECU tune. It's not a NICO ECU/tune. The "NICO" tune is only N/A and was tuned by Robert B years ago. I spent a lot of time road tuning this tune from scratch on my car to establish the baseline boost tune. Johns first stage is what I call my "summer safe" tune. I have ran this tune for years on my turbo Q at ~8 psi in the 110*F Phoenix summers with no detonation. Timing is retarded quite a bit from stock and fuel maps have been adjusted. I expanded the TP scales from a stock max of 72 to 128 because I was maxing this out easily under boost, now it has much more adjustability. His second stage has the timing advanced a few degrees in the load areas which his dyno charts indicate bumped up the HP a little.

John, not sure how locked in to your tuner you are but if you like I can program you an 8 way ECU that follows the same pattern as the first two stages. Each would advance the timing a degree or two in the load area. This would give you a fairly broad range of timing advance to work with. I'm not sure how your tuner plans to tune your ECU but I would recommend doing what I've done by adding an emulator in place of the EPROM chip. This allows real time tuning w/o constantly having to swap the 28 (or 32) pin EPROM chip out which is a bit of a pain if you do much tuning.

As for the injector duty cycles, I've logged up to 88% duty cycle at 7-8 psi @ 6400 rpm. I don't have AFR numbers during those runs but when I have logged the AFR numbers separately I've never been lean, just as John's seen. I always used my methanol injection though.

Exciting stuff! Did anyone shoot any videos of your dyno runs? I'd love to see, and hear, those!

Sorry about that... Yeah, I have video. The sound quality isn't that good, the building was huge, sound bouncing off everywhere. but here they are;

Stage 1

Stage 2

Shane, I absolutely love the tunes you did for me, but at this point in time, I want to have the car tuned on dyno with everything monitored. This guy worked for Nissan and has tuned VH's and has an excellent reputation. Please don't take it personal. I wouldn't have got this far if it wasn't for you Bud! :dblthumb:

If he tells you you have to purchase a new ECU be aware that you don't need that. A Moates Ostrich emulator is all you need to perform real time tuning. I'm curious what methods, software and hardware he uses.

Were you able to see the videos? Not exactly sure if it works. No new ECU, he just wanted to make sure it was 8bit, not 16. I wish my phone sounded better. A bunch of people left the garage area when I got up to dyno. Guess they thought, no big deal. It was funny as hell how people started running back in once they heard the car...

I will make notes for you. I'm waiting for transmission solenoids right now and I got the NISMO FPR installed, was going to set it on 50psi only to find my fuel pump took a dump. It may be the relay, with my digital set on 200, i"m getting 68.0; my analog on 100=0, I'm confused. Go figure. I also had to fix a water drip on the rear of the passenger head. So I had to rip everything off the top. Fixed water line, replaced all vacuum lines, fuel lines w/ 180psi rubber.

So after I get all this back together, hopefully I'll be back racing by next weekend. We're having a "cold" spell down here and everyone's hoppin'... Driving me nuts to half to watch everyone else.

I like this clip. I was messing around in traffic, my daughter was operating the phone. I just love the way the car sounds... Better than music to me...

That in car video is pretty good. You get a good feel for the response and sound. I love the sound too. Much of my time in the car I also turn down/off the stereo, the engine/turbo/blow off valve sounds better to me too!

Got to get some better videos tho, I'm dying to get some good footage of it! If I ever get back to your area I'll have to look you up.

Please do. The wife won't allow me to get too crazy with the kiddos in the car, wish I had a GoPro or something... I'll try to get more. BTW, having problems getting the NIsmo adj, FPR set, because the rails won't pressurize. Pump is on, TPS, IAC is connected, but everything on top is "off". I want to pressure check all the new connections before I finish it up... Any suggestions?

MY GOD your interior is clean! I thought my car had a pretty decent interior, but now feel humbled and ashamed. It doesn't look like anyone has ever sat in your back seats!

My car? My car isn't that clean... The new leather is what your noticing. I had the seats and door panels redone in leather, headliner, carpet and back tray cleaned.

The leather from the place on Ebay is actually pretty excellent for the price, but my lady could've done a better job on the headrests and a few other items. The guys broke a few things, even though I gave them my bible, FSM, to use. Total cost for it all; $1560.00.
