Joel, why a T-28 instead of a T-25? The 25 is smaller, and many many DSM owners are getting rid of them as they upgrade. Everyone is concerned about spool up. Im just trying to get this work in theory thinking this out. Im thinking bigger turbo because more reliable I guess. As mentioned the big watermelon. I am counting on the wastegate settings to limit to 7psi. Im not concerned how fast I can spool up yet but maintaining 7PSI without blowing the engine. T25 are nice but Im looking at this T3. www.turboneticsinc.com/t3.html |

Still saying :bye: to Joel's future 3sfe. This came from our newest member. His ideas is very promising. turbotrdcelica.proboards29.com/index.cgi?board=FI&action=display&thread=11134146943SGTEturbo Wrote:An easy route would be reading just boost pressure and rpm. This is what an additional injector controller does. This is the most practical route for forced induction engine especially on cars that are pre-MAP based ECUs like the 3sfe and 3sge. My plan is using an HKS AICIII for fuel enrichment and a MSD BTM to pull timing under boost. And re-gapped plugs from stock .44 to .39 or .35. Using two 430cc injectors from a third gen turbo Supra and a Walbro 190 lph in tank pump. www.autodesignhaus.com/tuners/hks/aiciii.htmOperates at a wider range of rpm. (1,000 to 12,000 rpm) Displays injector opening percent, engine rpm, & boost pressure simultaneously. It can operate on 3,4,6, & 8 cylinder engines by changing the cylinder selector switch. New function/simulation, GCC adjustment, and map adjustment features. Because it operates injectors by controlling the current, it can control both high and low resistor injectors as long as the connector of the injector harness fits the injector. New AIC III can control up to eight injectors. Injector harnesses are now sold separately. His suggestion might be the missing element in our equation. HKS AICIII for fuel enrichment As of now as I stated. I am still running hot white plugs with just the 3sgte plugs. I am running way to lean, so I get more boost and I will need fuel enrichment from HKS AICIII for fuel enrichment ~ I think thats it. ***Just thinking out loud**** Now ~if only I can config my httpd.conf file to work in my DMZ with ProxyPass /Reverse and ReWrite Rules to my SSL server. Darn it, I need a light bulb. Funny thing is I can LYNX to my backend webserver but not the full page with any browser. I think the application layer needs to be bridge for SSL.[/tt] |

In short, his solution is to get a standalone. If you do that, then yeah.. it'll work. But only if you have something other than the stock electronics for the EFI controls.

I don't think so, man. Not street-legally, anyway. There is NO way you'd be able to pass emissions running that rich at idle. Even then.. do the math. See how much fuel you'd actually need to run this reliably. at 20% capacity until WOT, on a 250cc injector, that's only 50cc's at 3lbs of boost or so, and even more until you hit WOT. How many cc's of fuel is necessary to balance out .5L's of an a/f mixture so it burns on spark, and not on detonation. The math CAN be done, it's just a matter of doing it. And even then, how rich can you run at idle and still have at least an 80% burn to be able to pass emissions?
Yes.. it's tedious.. but if you really want this to work, it's math that'll have to be done.

Yes.. it's tedious.. but if you really want this to work, it's math that'll have to be done. I failed emission here in AZ like 6times. I had to go out and retune my timing back to stock 10* buying a timing gun for like 60bucks. It was a hassel cuz with my current setting I pass in VA. AZ must be stricter. I knew you were going to respond about the balancing act and when I read your response to emmissions, I thought cracked my knuckles ** 2006**. I dont know if I will pass emission reset back at 10* with increase injectors. Can I ask a favor. What is the injectors CC/Poundage for 3SFE and 3SGTE. As for the math thing Turbo / SuperCharger / NOS calculator ~ avg download util is 14 dollars. You know where we can find a free util that runs on Windows? oh on Linux too. I replaced my NGK GTE plugs in my FE. Though they run alot better than the stock recommended FE ~ the GTE plugs came out coated white. Its probably lean because Im always driving at Hi-End. I drive 4000 and above. I rarely use 5th gear here locally on the interstate around Phoenix but I will use 5th gear for long drives. My habit of driving sucks up alot of gas but being a celica owner ~ gas prices dont bother me. This balance of low end plus hi end is like making a fuel econo fe with a hi performance ge setup. Hybrid FEGE. I will continue to seach for a boost calculator ` freeware. thanks. |

I'll look really quick.
the 3sfe is 295cc/min and the 3sgte is 440cc/min
(just got that info from Jeremy.. so, yeah. )

I just thought of something. If you run an MSD boost retard, you could adjust the timing to compensate for the detonation problem.. the only thing then, is how to program it so it's automatic. an SAFCII won't do that. I'm not sure what will other than a standalone.

I'm not sure what will other than a standalone. My understanding the MSD BTM will retard/adv automatically adjust to the dynamic boost for perfect detonation from 0* to 3* BTDC. Thanks for the info all. Cough *Jer* |

Cough *Jer* I mean you need to be able to program it yourself to compensate for the rich mixture in lower rpms and then readjust as the boost and fuel dump hits. |

Referring to this link: www.airpowersystems.com.au/unichip/unichip.htmAm I reading this right ~ this is a fuel managment that I can manually adjust or will it also control my ignition spark. Im confused. I hoping UNICHIP to do my fuel maps not my ignition thats MSD BTM part. I hope to use the both in concert. www.diynetwork.com/diy/ab_parts_accessories/article/0,2021,DIY_13690_3081612,00.html Piggyback Engine-Control Unit
The new piggyback engine-control unit (ECU) is an easy 2-bolt, plug-in installation that works ideally with the new air-intake and exhaust system to help boost power even more.
This particular unit is known as the Unichip -- but it's more than just an ordinary chip. It's a computerized modification that optimizes fuel and ignition curves to make use of improved airflow. The particular Unichip we installed was actually pre-programmed for the Toyota Matrix model featured in this episode. This UNICHIP piggybacks our ECUs. What is your opinion can I use it with MSD BTM. Or does this UNICHIP do both for the price of one for A/F where I dont need the MSD. Another fuel managment is AIC III.... this is getting expensive just for a FE> Currently today ~ Im running very lean using 3SGTE plugs. THe plugs are coated white ~ real white.. I dont have overheating problems at all car drives fine throughout the RPM bands. Think the UNICHIP will solve my current N/A setup? I probably will need to upgrade the injectors too, aye. Found this picture. Someone has already started the 3SFE turbo project.....  |

LMAO ~ Admin bending alittle there , Aye. Nah, if I fail this be my life savings. 5 Speed 700HP each SuperCharged / Turbo ~ I will buy Auto S/C for my wife and manual Turbo for me.  Darn, You hatting it. Aye. |
