REV limiter modification
We found that with the ECU upgrade, more power can be gained with a higher rev limiter. A 7100 RPM (stock 6600 RPM) rev limit is set to take advantage of top end horsepower, while still providing a safe protection for the motor.

Speed Limiter Removal
The speed limiter is removed. The stock limiter was set at 234Km/h (146 MPH), so for all practical purposes, we could have left it alone. But we decided to remove it, just in case someone feels the need to go beyond that.

Ignition Timing Map Adjusted
There wasn’t much room for improvement at the bottom end since the ECU retards a lot of timing by using a feed back system in stock trim. So, we have added more timing at the mid range - higher end to take additional advantage of higher-octane gasoline. This aids in improving torque from 3000 rpm and up.

Fuel Map Adjusted
Stock fuel was set to detune the top end horsepower. We discovered that the car runs extremely rich after 5000 rpm. Air to Fuel ratio (A/F) of 10.5 was found right before the stock rev limiter kicks in. Cleary, Nissan was trying to detune the power output at higher rpm to discourage the driver from hitting the rev limiter. For the performance enthusiasts, however, this is unsatisfactory, so we set the A/F to 12.5 all the way to redline to provide adequate power gain while still maintaining a safe margin.

Drive By Wire Adjustment
Throught our testing we found, the drive by wire system was program to never fully open (throttle flap) when you smash the accelerator pedal. In fact, it actually closes the closer you get to the rev limiter, by as much as 20%. This restricts air into the motor and causes HP and Torque numbers to go down. We have remapped this setup so when you go wide open throttle, the throttle flap fully opens and STAYS open, increasing HP and Torque.


Adding to above modifications, a few other adjustments were made to other maps to enhance the feedback function which improves power, torque and drivability. The resulting achievement is a remarkable improvement in driving feel, which is more than what numbers alone can tell you. We are very satisfied with the results and are proud to release our TECHNOS ECU for this tuning-challenged ECU, blowing the lid off what was thought to be an automobile already running pretty near its maximum capability.

Changed air intake system
One of the major problems on this car was a feedback system that compensates for modifications. The oxygen sensors detects fuel mixture and will tell the ECU to richen up or lean out the mixture. This correction factor was way too wide, so some performance components upgrades (intake, exhaust) would actually result in a loss of HP below stock!
We adjusted the correction factor to reduce that compensation reaction. Our tests showed consistent power and torque improvement following installation of an intake system.
We will be conducting additional testing on various intake and exhaust systems for the compatibility of our ECU. Although we anticipate a dramatic improvement per component upgrades, some may require custom tuning to take full advantage of their performance.

Crawford Plenum




Price - $500.00
Original Plenum Core Charge - $200.00 (Refundable)

Lead-Time / Currently 5 - 10 Days, based upon available core returns and inventory with Nissan.

One of the largest contributors to performance loss, is the starvation of air within an engine. While the majority of people would never notice such a loss within their own engine, we began looking for causes of such a sharp decrease in power within the upper part of our powerband.

There is was, staring us in the eye. This very attractive molded plenum tucked underneith our plastic engine covers.

We still don't know why such an aggressive angle was incorporated into the design, perhaps to fit under the hood simplistically? Regardless, after flowbench testing we found there to be a 30% difference in flow between the rear cylinders and the forward.

In taking the current design, and raising the forward portion by nearly one inch... we reduced that difference to less than 5%. This was a HUGE discovery and one that has proven itself already on the dynos, and in the hands of MANY Z owners.

Can also be purchased from Strictly Z for the same price.

Crawford Equal Length Headers


Price - $1300

High Temperature Powerdercoated - Silver

From preliminary prototypes to the finished production set in the car, Crawford's PROUDLY presents to you its EQUAL LENGTH HEADERS!

ANYONE can throw several pipes in, and make them equal length... though how smooth are those bends? Are they carefully designed? Do they just fit within the car WITHOUT rubbing? This is a HUGE issue for us, which is the explanation for our minute delays.

Crawford Headers are a DIRECT replacement of the OEM exhaust manifold. You DO NOT have to forfeit your cats if you wish to run these!

Updated dyno sheets will be posted as they become available after this cars dyno run on Tuesday, 28 Oct 2003. Notice the current numbers you see here are from the far more crude "throw-together" headers. We wanted to know if a substaintial enough power was going to be made, to make bringing these to the market realistic. In proving... the venture to put these final pieces with even SMOOTHER bends, thus MORE potential power... was sucessful!

What better way to compliment the other largest gain in NA bolt-on power current available on the market, The Crawford Plenum... than to pick up these and watch your power continue to soar!

Polished Crawford Plenum


Price - $1,100.00
Original Plenum Core Charge - $200.00 (Refundable)

Lead-Time / Currently 5 - 10 Days, based upon available core returns and inventory with Nissan.

Are you the Z owner who is VERY into looks? Very into "blingage"? Then this is the plenum for you.

We had an OVERWHELMING responce on the initial plenum. Though there were still tons of people who wanted
the piece, but did not care for the more simple "race inspired" looks.

That's fine! We at Crawford began doing research seeing how fiesable it would be to construct a polished,
more importantly a SEAMLESS piece.

What you are looking at is the original plenum, with MANY more hours put into it! Dual welds both on the inside
and out. Extensive work on grinding down each of the outer welds. Then finally having it professionally
polished.
