Bigger turbo first. If you need more Air.. then get some tomie cam's

I decided on the Haltech E11v2, I should be ordering it next week.

There is another system i have been looking at. Its called VEMS It originated from megasquirt. but alot better now. it uses a modified version of Megatune. http://www.vems.co.uk/ But i dont wanna cheap out when it comes to an EMS. Haltech E11v2 Autronics SM4 Motec M600 MicroTech LTX12s Any one better then othe other?

Nothing against the PFC at all. I was always interested in doing a flying lead harrness to get rid of alot of the wiring mess. And the PFC is a little harder to come across now adays. I am also not sure if a Z32 MAF will support the power i plan on making. I have a spare block i am building up, and plan on putting that in the car soon. Thats why i was looking at haltech/autronics. My car will also be Street/drag, i also have spoken to Geoff a couple times and he swears up and down by the AEM EMS...

Bumping my old thread!!!! I still haven’t decided what management i want to get And I am about ready to order it; I haven’t done so already because I have been working on some other stuff on the car. My local tuner is trying to steer me into a new system from the UK called VEMS. But I am not sure if I really want to go with something that there isn’t a lot of knowledge about and/or support. If I go with Haltech, I can only use the “E11v2” Right? Since it’s the only one that has over 4 injector drivers? The Autronics I think is just two costly, but then again the E11v2 is almost as expensive Any suggestions?

Fuel pressure Timing Spark plugs A/F Things to pay real big attention to !!!

Here are some pictures of my car.... http://www.skylinesaustralia.com/forums/in...162572&st=0 Make sure you check out the last page, for new pic's i posted. Thanks!!!

Hello every one Some of you might remember me having a problem where my car would make boost while not moving (not under a load) Well honestly i believe i still have that problem. But that is beside the point. Sine then i have replaced timing belt, set ignition timing to 15 degrees... etc... But while trouble shooting that issue, i decided to check the TPS voltage to insure that its correct. I understand that when closed i should be getting about 0.3-0.5 and when open i believe its about 6.0? But.... I get about 6.0 voltage when the throttle is closed, and as i open the throttle it begins to go up Then as i continue to open the throttle the voltage goes back down... untill its 100% I have a 90mm Q45 Throttle body using the RB25 TPS. and its an S1 RB25 the one clip from the Q45 TPS is differnt, but once clip is the same. The clip that is the same is the one i check for the voltage. So i tired the Q45 TPS hopping that my RB25 TPS might be defective but the same thing happens I plan on hooking up my consult that i just got up this week, to see what it reads for the TPS And compare that to what i get using the multimeter. But i just wanted to know what every one thought? remember i have a RB25 in a US Spec Nissan 240sx... And the wiring had to be converted to work. but every thing else is fine on the car.

I think the SM4 (Autronics) is really what i am leaning to. Because i know the tuner is really good. The SM4 will run me about ... 2,424.30 AUD (2000.00 US) Plus 72.00 AUD (60.00 US) for the trigger wheel And 193.944 AUD (160.00 US) for the ignition multiplexer Plus tuning... WOW... extremely costly I will still look into Haltech/Motec and see what the prices will before that.

Here are some random pic's .... The car is on the ground now, but its still not done... I am still working on it, so there is several things i need to do..

I got every thing back togetter.. but still having the boost issue. But today was checking the TPS signal to make sure thats right.. And its not. It reads 6.XX when closed, and like 9.XX when open. I have a serious TPS issue... I am still trying to work this issue out. I ordered a Nissan Consult, and it should be here later this week. Which should allow me to see what the TPS signal is. If i cant fix eather problem, they will just wait till i get my standalone then. I think if the TPS is reading that high.. that the car is sending a massive amount of fuel Which would explain alot of stuff, like the really bad hesitation, and the black when ever i rev it up a decent amount

Hello Every one, Some of you might know, i have what you would call a Silvia, with a S1 RB25DET. I am getting ready to pick up a standalone, and I can not decide what to get. Lets start off with my goal, i plan on making about 450-500HP (335.56KW-372.85) I am looking to get rid of the AFM (MAF) and switch to Map sensor also (reason why i don’t want a PFC) There will be all supporting modifications to handle the 450-500HP (335.56KW-372.85) goal. So that is not a problem The type of driving will be, Drag/track/street I was wondering what EMS to go with. Motec Haltech Autronics EMS Any other(s)? Price isnt to much of an issue, i just want to know what would be my best option. There is a Autronics dealer/tuner in my town. Which is a friend of a friend... He is 1 of 16 in the US the whole us. Which is why I am leaning to Autronics Any Advice is appreciated

RB26 fuel rail fits on the RB25. So yes, you can use a GTR(RB26) Fuel Rail on a GST(RB25) With Top feed injectors

You can always get an aftermarket Rail. HKS makes one. But i would personally recommend just removing, cleaning then repainting yours. Saves alot of money. and i am sure it will look fine. I have a R33 RB25 so i have side feed injectors. I plan on going topfeed so thats why i am going with a new fuel rail.

Power Enterprise belt installed Timing on point I am now waiting for some other new parts i ordered Like new Radiator, Fans and Cooling panel Once that gets here ill start it back up and see how things turn out. An other thing id like to mention is... being that i have the Greddy IM and Q45 Throttle body, larger IC piping and a bigger FMIC With the Stock T3. Do you think since there is alot more Air passing though the motor now that it would have enough load to spin that little turbo? Well updates to come !!!
