This car belongs to Marc from Simpsonville. He brought the car in last night for a tune on 93 Octane, and then a tune on E85.
Marc uses this car to compete in SCCA STS class races, so the engine is essentially stock, due to classing rules, with a few bolt on parts. Since rules on power modifications are so strict, he wanted to convert to E85 to gain any available horsepower. Marc competes on a National level in this car, and is currently ranked 3rd in the nation in his class.
Since he will be driving the car to all events, he wanted a 93 Octane map, as well as the E85 map, since E85 may not be accessible in all areas.
Here is the setup:
Stock D16a6 AEM Cold Air Intake Custom Header Stock Cat 2 1/2" Exhaust, through a Burns Stainless Muffler
Stock fuel pump Stock injectors
Tuned on Zdyne (Usually we recommend converting to OBD1, but due to class rules, Marc needed to run the OEM ECU.)
Here is the chart. The brown line is from the 93 Octane tune, and the green line is from the E85 tune. Notice that there are gains through out the powerband, resulting in around a 5% gain in peak power and torque.
The D16a6 is a low compression, low HP engine. Still, good power gains were had from simply swapping fuels and re-tuning. In a high compression, or boosted application, E85 will allow the tuner more freedom with ignition timing, allowing your engine to produce more power, with less risk of damage to the engine.
This setup belongs to Daniel of Greenville who brought over his car for an E85 tune this morning on Crome Gold.

Jessie's 240sx is finally ready for the dyno. His S14 SR20det had a good bit of issues(Wiring, Turbos, etc..) are completed and ready for a Nistune Tune. Look for the Dyno Charts this week.
Adam brought us his Mazdaspeed6 for a complete engine swap. Just after his warranty went out on his Mazda the motor blew and needed to get back on the road fast. The new motor arrived yesterday and the old one is coming out today. We should have Adam back on the road Wednesday.
Anthony's 240sx Coupe is starting to wrap up here at TDC. He recently had just purchased the car and brought it straight to the shop. Anthony had no idea what was wrong with the car and asked us to get it ready for him to track race the car. The Car was in need of a tune which is being preformed on Microtech. He was also having charging issues which was resolved. We are also installing a battery kill-switch so that the car is ready for the track.
Ryan brought back his Jeep for some more repairs. Ryan has been coming to us for the past year with all of his problems, and now he was in need of getting his a/c back. The compressor was completely gone and was screeching very bad. We replaced his old broken compressor with a new one and had him on his way the same day.
Jeff brought us his 1995 Cobra Mustang for some repairs, parts installs, and a tune on SCT. We started by repairing a "ticking" noise that he had, which turned out to be nothing but a broken spark plug.
Jeff had us replace his Shorty Headers with BBK long tube headers, install a BBK X Pipe, Trick Flow Nitrous Kit, and Autometer gauges and pod.
After the installs, Jeff's Cobra went on to the dyno.
MSD Billet Distributor MSD Plug Wires MSD Ignition and Coil
Tuned on SCT. As a side note, SCT for OBD1 Ford Cars does not offer datalogging, even though all of their OBD2 programmers do. On OBD1 Fords, we usually recommend Tweecer RT for tuning, but Jeff's ECU already had the chip for SCT.
Here is the chart from the motor tune:
This chart is without the Nitrous. This engine has a nitrous cam installed, which can have a slightly adverse effect on all-motor performance. After Jeff's bottle warmer is installed, we will tune for nitrous, and post those charts as well. Be on the lookout for update!
Mai brought us his Civic on Friday for a few repairs, some parts installs, and a tune on Crome Gold. We installed his AEM Fuel Rail, Resistors, DSM 450cc injectors, chipped his OBD1 P28, and installed a jumper harness. After deciding that he wanted to go over 8 psi, we also installed a GM 3Bar MAP Sensor.
His swap and tune was completed by another shop, so Mai asked us to look over the wiring, since the car had given him a few random issues. Mai told us that his car would randomly "skip", and was not making the power that he thought a turbo car should. Here is what we found:
Notice that not only are there 3 crimp connectors in the injector wiring, the clips also have wires soldered onto them right at the base of the clip. All 4 injectors were rigged up the same way. Can anyone say "fire hazard"?
We replaced the entire injector portion of the wiring harness, soldered and heat shrinked the inline resistors, installed the injectors and fuel rail, and got the car on the dyno. This car was also previously tuned on a VAFC, with the stock injectors, so in the sake of safety, we did not do a base pull.
Here is the setup:

Here is the dyno chart for low boost. Boost levels were fluctuating between 6.8psi and 7.1psi.
Here is a chart for 10psi, but the clutch started slipping badly on the dyno. This run was ended early, and the dyno session was stopped until the clutch is replaced.
All the parts installs are finally complete for Jeff's Mustang GT. After repairing a ticking issue he had we installed long tube headers, Nitrous and Volt gauges, Trick-Flow Nitrous Kit and last but not least will be the Tune on SCT. Nitrous will be sprayed on this car eventually, but for today we will only be tuning the motor. We will have the charts up here soon.
Austin's D2 coilovers made it in this morning and are on. It completes his maintenance that was started yesterday for his trip to school. When he returns he will be ready for the turbo kit that he has been wanting.
Jeff's Mustang has the last pieces for the build he has started. Gauges were the last touch for tuning the Nitrous on the Mustang. We will have the sheets up when this car is tuned. One on the motor and one on Nitrous. Be on the look out for it.
Tim brought us his Integra a while back for a few repairs and a tune. The first time on the dyno, his car was tuned on 93 Octane, and had a few boost controller issues. He brought the car back this week, and we installed a Blox Fuel Pressure gauge, AEM Tru Boost, removed the 93 Octane and switched over to E85.

The only changes to Tim's setup were the AEM boost Controller, Blox Fuel pressure gauge, and E85.
Here are the charts, tuned on E85. First is 13psi, second is 17psi, and 15psi, respectively.
The injectors were seeing really high duty cycles at 17psi, so we left the boost controller at 15psi. Tim may be adding an inline Bosch 044 pump to supply the extra fuel capacity needed for E85, and turning the boost back up.
For comparison purposes, here is Tim's chart from the last tune on 93 octane vs. the chart from the E85 tune. Both of these charts are at 15psi.
Tim brought back his 01 GSR Integra for some more upgrades. He decided it was time to convert over to E85 and add more boost. We installed an True Boost Gauge with a Blox Fuel Pressure Gauge. Car will be re-tuned tonight and will have dyno sheet tomorrow.
Austin has been a long time customer here at TDC and wit him heading off to school he needed some maintenance. All new breaks and rotors, Serpentine belts, Radiator flush, and a new Comp Stage 4 clutch. He just ordered some D2 Coilovers which will be in tomorrow.
James brought us his Turbo GSR for tune yesterday. The car was tune with Crome Gold and used E85. Pictures were asked not to be posted for safety reasons.

Josh was in need of some coilovers after just purchasing his new 2010 Honda Accord. He bought new D2 Racing Coilovers from us and had them installed. 2 finger gap is what Josh asked for and we also had a full alignment done for perfect driving.
After the Coilover install
Anthony had heard of us on the internet and decided to bring us his Nissan 240sx SR20DET race car. From Columbia, Josh needed a install and tune on Microtech. Also with that he needed us to clean up some wiring issues, with a new alternator install and an engine torque dampener installed. Car should be ready to go in the next few days, look for the dyno sheet.
Jeff's Mustang is getting close to completion here as a few more parts are being installed before the tune. BBK headers with an X-Pipe to finish off all of the parts installs. Next week the car will be on the dyno for a tune on SCT. once the car is running and Jeff drives it for a while he will be back for a new tune on E85 with a chance of more nitrous.
Cody is back again with a new setup on his car. His Civic Hatch has ben here for 4 tunes, all different setups. This setup consists of a High Compression Motor (13:1) and Turbo. He has high hopes with a goal of 400whp for this setup which should be easy to obtain. Will have some dyno sheet tomorrow.
Eric's Subaru is coming close to being finished. The motor is in running condition and now we are checking over the drivetrain to make sure everything is set for driving conditions. This car came to us in parts, in a bucket, in the trunk. One other addition to this car will be a front mount intercooler which will make this car complete.
Jon's Camaro is ready for a tune. The car is running really rich, which is giving Jon major drivability issues. This car should make really good power and we are all very excited to see what happens.
And here are some of the picture of Adam Seaman at Elite Summer Nationals.
Adam's GT Mustang was in here for a new Comp Clutch after a long weekend of drifting. Adam competed in the past weekends drifting event at Elite Summer Nationals. We are currently getting ready to put a V8 swap into his 240sx. Car should be ready next year.
Jeff was so happy that we fix his problem with his Mustang Friday so he decided to have us put the Nitrous Kit he had just recently purchased on. He also is ordering Long tube headers, new exhaust and a few other upgrades before the tune is preformed.
Jon's New Turbo Camaro is here for an oil change and a new exhaust. All this is being done in preparation for the tune tomorrow. Be on the look out for the numbers on this car as it should be 500+whp.
Jeff Brought us his 94 Mustang GT For some repairs and a tune. Jeff has a ticking noise that is coming from his motor. When that problem is corrected he would like to maximize his setup with a new tune. Last time she was tuned it made 400+whp. Be on the look out for the dyno sheets.
TDC has taken on a new Project. We was brought an 1980 Civic that will be converted to OBD1 and have custom mounts placed in it for the GSR motor swap that will be going into the car. We will be documenting this project alot so stay tuned for the progress on this car.
Jesus is back with his Turbo Prelude for some work. Originally Jesus had came to us a while back for a turbo kit and a tune on Crome Gold. Car made right at 300whp which is very nice for a daily driven car. The Prelude has a small oil leak on the oil pan which we will be fixing and Jesus would like us to finish off his exhaust as he was running with an open down-pipe..
All this week, through next Friday, we will be doing dyno runs for $25. This includes 3 runs, and can only be during normal business hours. Please call ahead if you plan to come during lunch hours.
James brought us back his Nissan 300ZX for a fuel pump install. James 300ZX has been to the shop a few times for some routine maintenance. This will be a quick install and have him out today.
All this week, through next Friday, we will be doing dyno runs for $25. This includes 3 runs, and can only be during normal business hours. Please call ahead if you plan to come during lunch hours.
Smurfs motor is torn down and here is the damage. We had known it was a rod knock and discovered it was the 3rd cylinder. The rod was heated so hot, it changed colors. As you can see it was gray now it is blue.
Alex's parts are here and it is time to install them. Alex was having oil pressure problems on his SR20det.So he decided to install a new OEM Nissan Oil Pump with an Autometer Oil Pressure Gauge. Next Alex plans for more boost with Nistune for a fun weekend warrior.
This car belongs to Stephen from Greenville. Stephen brought us his Civic for a tune on Crome Gold last Saturday. After a few small issues on the dyno, he brought the car back today to finish the tune. This car is his daily driver, and retains both power steering and AC. The exhaust was routed through the stock muffler, and the BOV was recirculated to cut down on any noise.
