is that the greddy type-s you have in there?

can you post a pic of where the knobs are set? ive been playing around with mine today, and want to see where you have yours at for comparison.

car looks nice. i like how bone stock it looks right now. but clean up that engine a bit. paint the heatshield. it will do wonders for the engine bay. i bet those stock wheels are really easy to spin. haha

your a/f ratio is a little too lean and you did get detonation in that run. probably because its tuned too lean . there really isint much fuel to work with on a jdm ecu. it normally runs at a nice 11.5:1 ratio at 15psi and thats perfect. whoever "tuned" it, was probably just trying to lean it out and much as possible to give you some type of gain from having an sm6 in there. problem is, that when u lean the fuel out, the ecu advances timing, and this is a BIG no no. you said the a/f ratio has been good all day... do you have a wide band in the car?

oh btw,... your new redline is 7,300ish, not the 6,3000 the dyno driver was hitting.

Actually, that took quite a bit of leaning out (not to mention that most of all the rest of the runs were at 11.0 and it was creeping up with heat soak because we were back to back thrashing it). Even at 15 PSI when the car pulled 240 untuned, the A/F was dipping below 10:1 and we had done nothing but turn the boost up. It was HORRENDOUS on the factory boost. I've actually added a bit of fuel back in up top and taken some out of the part throttle ranges because I was seeing spark knock on the highway at the top of the powerband and the part throttle driving was just pig rich (typical black puffs out back).

There really isn't a point to take the motor to 7300 RPM because the power and torque were both dropping off at that 6300 where the driver was shutting it down. No reason to continue to spin a motor harder when there's nothing to be gained by it. Once we toss a CT27 on there and see how high it pulls........well.......

Engine bay is being worked. I'm scheming. I'm ordering all black couplers tomorrow (still have a couple rubber ones on there) and am planning on having the heat shield and possibly all intercooler piping ceramic coated, and want to do the valve cover in black, and then polish anything that's left over. Simple black and polish looks, no colors, just a nice understated engine bay. I'd actually like to get my hands on a manifold to polish while I'm at it.

And it will blow those stock tires away. Tuesday I'm mounting the new tires to the HPR5's (215/35's on an 18x8) so we'll see how those fare. Then it's some E.T. Street Radials for a pair of the stockers for some stickiness at the track. Broken parts here I come.

Yeah, I'll get you a pic tomorrow and post it up for ya.

thats totally normal. your vented bov is to blame for that. you can try to tighten the nut on it a little bit. it should help out a bit.

exactly how much fuel was taken out overall?

do you know if your smt6 has the afm to map option, or was that only in the smt7?

i thought you said you never saw a dyno that can log boost? lol . its awesome to see that the greddy type-s holds the boost fairly even. i know jeff has some issues with his profec that uses the same selenoid as us, so i was worried about mine. good to know it works well. what was your peak boost on those runs?

[lagos]

oh and make some vids of those gauges once u get them hooked up . i really want to see them in action.

[Fastbird]

i thought you said you never saw a dyno that can log boost? lol .

Never seen a Dynojet that can log boost.

Max boost seen on my runs was 16 PSI.

Here's a shot of where Dr. Tweak set it:


And an update on those gauges. Right now as installed in the pod there's Boost/Vac, Oil Pressure, and Fuel Pressure. Silly me didn't research the fact that Toyota didn't put a schraeder valve on the fuel rails, so there's no easy way to install the Fuel Pressure gauge. So...............I'm pulling that out as soon as the new gauge comes in:

Figure with the datalogging capability of the Nexus gauges coupled with the SMT6 and a good TPS hookup, I'll have no trouble doing some no bs real world tuning, both part throttle and wide open. Coming soon to a swap near you.

*Edit* Scratch that. Just found out why no one seems to have it in stock. Not being released until Mid September even though they were supposed to be out in the spring time. Dang it.

good stuff man!
be carefull with how much fuel you pull with the SMT, if it doesnt control fuel seperate from timing..although im sure youve been over that before.
good luck and keep us updated on the tuning as you go!

Sean:

What happens in a race between the vette and the celica from 30-60mph?

Not sure yet. Vette has a flat tire and I'm waiting on new wheels and tires to come in. Figure that the vette is making ~50 more HP than the celica, has more of a cruise gearing, but the LS1 is also a top end motor. I think that the Vette would initially get down a little to the Celica, but would catch up and overtake in a heartbeat. Figure it's good for low 13's high 12's @106-108 as it sits, and the top end is where it really shines.

Stinking autometer. I'm so irritated about the wide band being pushed back.

[lagos]

if the vett is only making about 50hp more then the celica, then the celica stands a good chance. it sucks for 1/4times but does really well from a roll with its power to weight ratio. youll be surprised at some of the cars youll be able to beat in it

[Insanity-74]

Looks fantastic, but I would lag your downpipe....will help stop heat transfer to your intake air as the intercooler pipe looks like its touching the exhaust.

[brianforster]

400$ for a wideband gauge? does it come with a sender?

[Fastbird]

Explain "lag." FWIW, the intercooler pipe that's touching the downpipe is pre-intercooler. I'm already scheming on a way to seperate the two.

400$ for a wideband gauge? does it come with a sender?

Yeah, that's gauge, sender, brain, and will hook right into the nexus system via piggyback for visual control. That's pretty much the standard price for any decent wide band with logging capability (in this case, logging via the nexus control module along with any other guage connected).

[brianforster]

im confused it hooks into what nexus control module? is that who makes the smt6?

[Defgeph]

Nexus gauges I cant wait to see them!

[brianforster]

holy **** i just read up on the nexus gauges, thats amazing, me want me want

i guess future plans for me will involve nexus boost and nexus wideband gauges that controller unit dohickey..

god you have like 1k in gauges on that car, lol.

[zipstrips]

i LOVE seeing how your exhaust is run! i need to move mine over now. i ran my over axle when the stock runs and it interfers with the control arm movement a little........ i originally thought i should use that opening in too.

I actually picked up everything on eBay for about $780....but subtract $200 because the fuel pressure gauge won't be going in (will go into my Trans Am drag car instead ) and add in $400 for the Wide Band when it's released, so actually.....jeebus. That's almost $1200 in gauges. These things BETTER be worth it.

I'm not getting any interference with the A-Arm movement, but I do get some clunking every now and then when doing some "spirited" driving or going over your typical NJ bumpy roads. I'm going to replace the old saggy 130K mile rubber hangers and probably take my old rubber couplers and put them around the pipes as "padding" where it's contacting. I've already checked and the exhaust doesn't get very warm at all back there.

[lagos]

dang, you got 130K on your 99? i only got like 66k on my 98. maybe i need to do more driving haha. did you 5sfe still run when it was taken out?

[Fastbird]

It ran, but Dr. Tweak was amazed that it did. FWIW, I bought the car with 114K miles on it in July of 05 from the second owner who had only had it for a month (old guy, too hard to get in/out of). By the time we took it to Doc, it had a valve tick and was burning a little oil on startup (thinking valve seal). Ran like a champ the entire time though.

[brianforster]

how much did you pay for it?
