Lambda Control

Lambda Control



I have been spending some time lately with Paul at YawPower.com on tuning the M2R. He is a MoTeC dealer and knows the software pretty well. At first, things were happening like magic. I gave him my map, he went over it and sent it back. The car was immedietly running better and he'd never even seen my car!
He convinced me to purchase the advanced tuning options, and we enabled lambda control. This is a pretty sweet feature, and you can read all about it HERE. We were having some issues with the lambda input coming from the AEM UEGO controller. We went through countless hours with a multimeter, and re-tracking wires; and all to no avail. The AEM gauge/controller output (in voltage) NEVER matched what the manual said it was supposed to be.

I got seriously pissed with this product, and tried using their Tech Support. They basically told me that I was wrong... So I sold the unit the next day, and traded it in for the Innovate LC-1. Unlike the AEM, I can actually program the output of the gauge to what ever voltage scale I want (AEM only gives you 5 modes).

I have yet to install the LC-1, but will hopefully have it in tonight. The tuning is coming along pretty nicely on the car, but without a proper lambda reading, I'll eventually need to go over some of the map again.

Here is the digital gauge it came with. I outputs the same lambda readings the MoTeC outputs, but the decimal point is moved to the wrong spot. So instead of reading .98 it reads 9.8. I'll mount the gauge, LED and reset button over the stock boost gauge.

She was running well for a while now, but I recently toasted my 20 year old coils. I've got some MSD blaster 2's on the way. I've also noticed that the turbo is slightly leaking into the intake track. I'll need to rebuild that thing soon. It's hard to belive I've spent so much money on a stock turbocharger. That think has been ported and coated, and soon rebuilt... WOW.

I've also got a friend making me some new motor mounts and a new differential mount. Hopefully, I can add methanol to the intake in the next month. After that, she should be solid and ready for a track run. Here are a few pics after a wax. (I know, the paint needs a buff, but it aint too bad)

Here are some pics of the PERFECT s4 stereo surround. I got this for $5 at the junkyard. The two screws behind the vents don't match up, but it's hard to tell.

I switched back to the s4 shifter surround because the rubber s5 one doesn't fit with this stereo surround. I am also using the s5 vents. They actually don't fit in there perfectly, but as long as I'm not launching, it stays put.

Now stereo for now, but it still looks clean.

Just another detail shot of some of the s5 interior peices fit in my s4.

The series 5 b-pillar trim didn't fit, I painted the s4 b-pillar trim so it blends in a little better. The plastic wheel well trim fit. but I had to trim the bin support to make it fit.

Christmas In May

I came home today and had 3 packages waiting for me.


First, there was this V-Mount intercooler setup I bought from need-a-t2. It's a GodSpeed intercooler that ready to mount up to the stock turbo and can be easitly modified for an upgraded turbo.

The set-up came with this TurboXS blow-off valve and Higgi throttle body elbow. Also came with the piping and clamps. Sweet deal for me! I probobly won't put this on just yet, but I couldn't pass up the offer.


I also ordered a new clutch master cylinder and slave cylinder. This came from SpooledupRacing on the Rx7club.com.
Also, pictured above are some used stock injectors I got from boost_its_what_for_dinner. They are 550 cc high impedence injectors.

"Under" Rated

"Under" Rated



This is my new Rotary Performance Under-Drive pulley. It had timing marks that will greatly add to the tunability of the car.


A little stumble in the road to boost:
One of my stock injectors started leaking from the part that clips on to the harness.
My clutch hydrulics are shot. Before, we could shift with some difficulty, but now it is near impossible.

So I've got a pair of stock injectors on the way from boost_its_whats_for_dinner. I ordered the clutch hydrulics from SpooledUpRacing. And I ordered a new harness and sender for my oil temp gauge. The current one is leaking becasue it's the wrong one.

FD Alternator

FD Alternator

I got this FD alternator fc3s91 on the RX7club.com. He included the Rotor-shaped pulley with the deal!

It's freshly rebuilt and was polished. This will allow more amps to flow into my car and support an e-fan.

Back Where She Belongs

Back Where She Belongs

Well she made her way back to my garage last night. We bought this house after the car went in the shop so she's never been to this house.

But she is drive-able. Still a little rough, but drive-able. I have an FD alternator and dual pully on the way and will be taking the car out for fine tuning most everynight this week.

It's ALIVE!!

A couple broken 7's. For once, mine is the closest to being finished.


K&N air filter. I ordered it from thier website. Man does that site suck. I really wanted a filter with element on the top.


The wideband is wired up. After the tuning is complete, we will get the wideband connected to the ECU as well.

Here is how the NA throttle cable hooks up. It has improved throttle body response and eliminated a long cable that wrapped needlessly around the entire motor.

To do this mod, you need to reverse the butterflies on the throttle body linkage. Then, you will have to cut the metal stopper at the end of the cable. Once you cut it to the proper length, drill a hole on the stopper and silver solder it back on to the end of the cable. Last, make a little bracket for the cable to connect to and mount to the throttle body.

Minor Stuff

New wires for the leading coils.

Huge MagnaFlow muffler. It is really pretty quite with just this one, but has lots of bass. I may end up adding one more muffler.

Intake piping is finished up. Now I need to order the k&n.



Pulsation Dampener delete, complete.
We've been trying to get the car started the last two weeks. This Motec ecu is a little more complex than what the shop usually tunes. Hopefully we will be at the end of the road soon.

This is the lowest setting for the coil-overs.

Here is where the new battery cable comes out.

And the tube for the vent in the sealed box.

Here are all the gauges that I ran probes for today.

These are the new gauges I got from Turbo 3. A little ghetto rig until I can find a gauge pod for the idiot cluster.


The rear interior is all installed. I've found out the hard way what interior parts are interchangeable and which aren't.

Motor is just about done.

I ran a bunch of sensor through-out the car today. Here is the thermocouple and o2 sensor. Both lead inside the cabin to the appropriate gauge.

Water and oil temp gauges.

A nice close look at the oil fittings and lines.

These are the motor mounts my friend made for me. They are actually only a little stiffer than stock and I will need to put the metal cups back on.

Oil Filter relocation is complete.


Out with the old..

In with the Koni's. I was playing around with these on the car today and they are SO easy to adjust. We put the ride height at max and min just to see how it looked. I think I'll be setting em on low.
