On older ECU's the easiest way round this was changing the Clock rate, though it can have adverse effects. Not sure if this can be done the 7m ecu the way it can on the 4ag ECU's for example

Out of storage for a spring clean

It dosnt matter what the VPC was from, as they all use different wiring configurations for different types of AFM, As long as you use the wires emerging from the VPC and not those on the second plug. Just repin the second plug so you have connections to the 4 wires needed (and ensure the dip...

Long shot but would anyione have the timing card info for the HKS Intake/exhaust cams for the 1jzgte, have a feeling they are the same as the HKS 2jzgte Cams :- Intake valve #1 should be open by 1mm (.039inches) at: 256: 6deg ATDC 264: 2deg ATDC 272: 2deg BTDC Exhaust valve #1 should...

PS I know that fuel cut is dependant on other factors such as TPS, RPM, AIT, Coolant temp, but was wondering if these factors may be incoporated someway into the VPC's logic as it processes RPM and TPS and Knows the Stock ECU's AIT is locked at 32degrees?? (2.2K ohm resistor in pace) Marty

To cure my own Curiosity, could i ask anyone who is Running both VPC and SAFC (i know most do run these in tandam to help clean the vpc signal) to Monitor the SAFC's Karman signal and see if the VPC is clamping it at all during high boost Marty

The VPC merely reproduces an AFM signal, the stock ECU controls the injectors like it normally would. The difference being the stock ecu will never see a Signal from the VPC above fuel cut (apart from reasons mentioned above) Depending on the ROM fitted, the signal is scaled to the injectors...

I used to run a VPC with 680cc injectors, used the gain to remove as much fuel as possible fuel before tuning with an safc. ITC trying to control timing, and ran 23-25psi with no fuel cut. Have always advised against using an FCD in conjunction with the VPC as you dont know what effect this is...

Please bare with me as i try to explain how i have understood the magic box to work.... The VPC ROM holds a lookup table referenced via RPM and Boost which is accessed by the VPC and sent to the stock ecu The data in each cell of the table is a Karman Frequency value ....Just like the...

Hi, Looking for any real world experience of either 4088r or 4067r (PT) turbos on the 1jz. Car will be running mild cams (264's) hotside? positive boost by? max boost by? dynos would also be helpful cheers Marty

Stock engine anywere between 150-170psi *all cyls should be within 2-5% of each other Limit 125psi

So weres the Motec :naughty:

Thats Supraad's car ENGINE Blueprinted, Re-bored block and skimmed, lightweight and balanced crankshaft, Forged eagle H-beam connecting rods, ARP rod bolts, JE pro series forged pistons 0.40 oversize, JE plasma molly racing rings, ACL duraglide main and big end bearings, ARP main bearing bolts...

Well as i said, it works for me, even though that may be going against everything said on these forums. I will be fitting this to a my own hood soon when i find the time :icon_bigg http://i22.ebayimg.com/01/i/000/b5/8f/3e45_1.JPG

Poodles, i know this subject has been beat to death. And im not going to get into a discussion about it. i will continue to run my 7m's this way. I have never had any dextrimental effect on cooling whilst the car was driving, and considerable lower under hood temps while stationary or in slow...

Do you know thats one of the ways to reduce under hood temps (with bulk head rubber removed) ??

Stick it on your Fedex account Rich :biglaugh: would love to make it myself, but my dream of the getting correct lotto numbers couldnt be furthur from the truth this week :(

Euro Spec GT42r

Basically an adapter plate to mount the ITB's to the head, similar to the one in the pics, but prolly at a 35 degree angle. If your running Speed density i.e. maftpro, VPC etc etc, there is a Vac port on each ITB, you connect each one to a Vacuum manifold, and use that as your sensor reference...

Now this looks the Dogs! That would make an amazing FFIM with amazing throttle response on the 7mgte
