my mods SAFC2, 640cc injectors, MBC 14psi, walbo, adj-FPR, AEM wideband, and forged internals .20 over. i recently got it back together and was wandering if there is some settings on the SAFC2 to get it to run not so lean? it will be good when i first start the car up at like 11.3-11.6 AFR. ...
I have the Maft version 1.0. The problem is I have been hitting boost cut around 10 psi, on a Greddy TD06. When I first had the car, it ran sweet. Now, I hit cut pretty regularly. I reset the ECU and let my Maft re-read itself. That day it ran awesome. My question is I have heard that the...

Obviously this will be in progress for a long time....but here we go. This info if a conglomerate of stuff printed in manuals, found on the internet and pulled from my own head. Enjoy! Part Throttle AFR Tracking The idea behind Part Throttle AFR Tracking (PTT) is wide ranging. It allows you to...

yeah, this won't be done for a while.... Timing Monitor The MAFT Pro is capable of monitoring timing advance/retard via the MAF input when used in speed/density mode. In order to enable this, you must disconnect the MAF input pull-up resistor (R7 on the back of the MAFT Pro PCB). You can either...

I'm having problems with getting the car to run right. At idle it will go very lean...like 19:1 cold. Once it warms up it will run between 16:1 and 18:1. If i give it some gas it will rev, go rich(10:1-12:1) then fall to idle and try to stall (19:1 AFR), then eventually go back to around 17:1...
so im in the planning stages of my build and trying what piggyback system im going to use. im shooting for 400whp + a 35 shot of nitrous im just wondering if anyone has used the aem fic because it does timing as well as fuel which would be good where i plan on going both more boost and nitrous. ive...
Looking to see if anybody has an available map they could email me. I am using the base map from the mapecu CD and the car runs far to rich for my liking. I am looking for something a bit more stable so I can start tuning the car a bit better. Basic mods on my car 1989 7mgte 70mm turbo...
Im not sure if this should be posted in piggyback or the ecu section so sorry in advance mods if it has to be moved. I've read that when using for example an safc, where it allows you to tune the amount of fuel by altering the maf signal to the ecu, that when you alter the signal, the ecu adjust...
trying to force open loop for maftpro ptt here and for the last 3 days pulling the nbo2 sensor has worked perfectly. However tonight i went to get a few logs and the ecus showing a vf signal and tossing my tune out the window.... anybody seen this before? o2 is not on the car! 89 7mgte stock...
I just installed my safc2 and need some help initializing everything. It seems the same as the safc1 but with more varaibles. I bought it used so it was set for a mitsu gsx.. I changed the cyl number 6 not sure what the arrows are for though? Also what would be good setup for ne points? Appreciate...
so all the wires are the same as safc1 correct? Except the knock sensor hook up right? Does it matter which knock sensor i tap into 1 or 2? Thanks
OK i am running 57trim, 560cc, lex, 2.5 ic kit, 3.5" turbo back, afpr 36-38psi, safc2. altitude 6600, and wanna run lower boost with more power (10-14psi) if possible I have not had a chance to get back to the dyno for a retune, and my tuner is not all that knowledgeable of safc. He has it set a...
I was just curious if anyone had a different map for a 7mgte supra with 550cc injectors that the one supplied off the mapecu website. Let me know if you do, it would be greatly appreciated.
I just installed 550cc injectors and the VPC installed and and a new turbo. I can not get the car to idle correctly no matter what I do and anything less than 2000 rpms is worthless it just leans way out when i hit the throttle and often stalls. I'm not entirely sure where to start. I have been...
ok i'm looking to find out two or three thing's i'm haveing an issue with finding all the info on stanlling this SAFC2 (Blue) I have my grounds,power,afm,tps. and yeah thats it. The thing thats getting me is the two rpm wire's. \And the two knock sensers do i just spice the one andif so which wires?
Hello all, I need some help on finding the correct post/link to wire in a apexi safcII into my 5spd 89 turbo MKIII I have been everywhere and can't seem to get the correct info for my application. I found some posts that say that the apexi web site has incorrect info on the wiring diagram. I...
Well I bought a used emanage blue off my friend and installed it recently and it doesnt work I bought the support tool and everything my pc wont communicate with it am I doing something wrong? im using dl'd software from revspec.com
One of the options on the maft-pro is to use Enahnced TPS. This takes the TPS signal and sends it to the ecu like normal. Once a set threshold is crossed, it sends an altered TPS signal to the ecu. You can set the threshold by either RPM, BOOST or BOTH. How fast it does the signal switch is...
Yes I searched in the MAFT-Pro sub section already. I know v5.03 of Maft-PRO allows you to change the RPM & MAP axis points. However when I changed them in the BIN/front-end it simply changed the label on the VE Table in TunerPro RT. Even after turning off & re-enabling ALDL Tracing, the same...
i dont own a supra, nut i know alot of people with supras use this computer set up, or so ive been told. im just looking for a bit of help. i recently purchased an HKS PFC FCON and FCD combo specific to a Celica AllTrac whic is what i drive. the only thing is, it did not come with the proper...
Below are four logs and here's a brief overview... Log #1 is at 12psi. Log #2 is at 16psi Log #3 is at 16psi Log #4 is Logs 2&3 overlayed What I'm concerned about is what happens at rpm ~4800. At 16 psi there is a dip in AFR's and timing. This doesn't happen at 12 psi so is the ECU...
what are the differences between the hot wire, pressure, flap and karman sensors, which is used in the 1jz and what do the sub menus for each sensor do? thanks
so, i installed this thing according to the manuals that i could find for my car, and the car wont start with it installed. everything is zeroed out, and the unit is powered up. i triple checked all the wires, and also called apex-usa about the problem. it still doesnt work, i was wondering if...
