Congrats man.
MAPECU guys made me a custom 2,5 meters harness to put the box inside the cabin of the car.
Where did you install yours?
Are you going to install the AFR calibrator also?
Did the car start with the base map?
Why you had problems with the timing?
Pulling some degrees at high rpm makes the engine rev more freely.
Our engine's knock sensor does a great job on timing adjustments but on open loop the MAPECU3 is able to do the trick.
I have also installed a water/meth kit that helps a lot.
Congrats on your project again and hope that more guys will follow.

Yes, I need to find some time to install this wideband. I just finished polishing up the lower plenum,cleaning the 85k worth of gunk off the valves and seafoamed the upper plastic portion by hand with a long flexible brush. It feels REAL strong today.
I'm really not sure what was necessary to get it to start. I wasnt there that day. I think mapecu may have sent him something to start with? I'm really not sure.
THanks pepos, I appreciate all of your advice.

So I've seafoamed my manifold, polished up the lower plenum and installed my wideband into the mapecu. According to my logs, I'm still running about 11.4 at redline. I dunno if the shops afr reading was too high or what, but I'm gonna schedule another time for a tuning session to see what we can get.

What's next man? I'll be trying to go for this mod after I get my Low CR pistons installed and work out any bugs they carry with them. Would you mind If I bugged you for advice on this when it's time?

I've added 4 degrees of timing since the last dyno and played with the air/fuel on the street and it sticks near 11.9-12 at redline which is fine with me. It feels stronger, I just havent had time to go dyno and prove that 300whp is in there
Most of my expendable income has gone towards setting up the business, but I am torn between sticking it out and trying to be the fastest N/A or just going for it with a rear mount turbo and custom pistons, etc.
If I go N/A, Id have the plenum and whatever portions of the head I could ported and polished professionally. I did some polishing work but, it isnt great. I'd probably get real lightweight tires and drags, a carbon fiber driveshaft, and basically weight reduction where I could but still maintaining some sort of Lexus feel.
ORRRR
I keep everything how it is and let my car be down for probably months and months on end while pistons and rear mount turbos and $$$$$ goes flying out the window.......
In all actuality, I'll probably just have to let my car be for now. The business is much more important and I'm on the cusp of really kicking it off. I've got new products for the Lexus GX470 including a roof rack and full steel plate bumper, so I am giving it all I've got.
Who knows, I might sneak in here and announce my 300whp claim one day.....

I'm used to seeing low 11's for the A/F on boosted car...but is 11.9-12.0 healthy for our N/A motors? Curious now to see what a totally stock A/F might be on these things. Sold my Innovate WB along with all my Honda turbo stuff a while back...wishing I had kept that WB setup.

totally stock usually dips into the 10's at about 6000rpm
I'd say 12.5 is about as high as you could go. I've been running 12~ for more than 6 months with absolutely no problems.

I've moved back to 5.5psi on the stock ecu and rarely do I see a 12 a/f...but I also dont get rediculously rich 10s either. Its a happy median but some type of EM is in order to really get gains from whatever setup anyone is running on this car. Makes me want to try the map ecu but I just dont have the time to play much right now!
Do you ever knock!?!?!?

no knock ever. This motor likes it lean.
yeah, I'd be concerned with a 12.5 under boost too, but N/A.....she can handle it.
I've seen it hit 13~ in 2nd and 3rd and it just keeps getting stronger and stronger. When I get my new tablet I'll do a few runs so y'all can see the logging of the MAPECU

Lol LC pistons come cheaper than you'd think.
