ECU Tuning Service

Since 2001 R.S. Enthalpy has been perfecting the art of tuning ECU's for 240sx applications.

Each ECU is custom tuned for your specific application using the extensive experience that I have developed tuning
SR's and KA's both in person and with mail order tuning.  I never stop learning and I never stop searching for better 
ways to tune.  My tuning methods have proven themselves time after time by running better and making up to 30 whp 
more than the competition. 

I also strive to excel at customer service.  I understand that you love driving your car and don't want to be without your 
baby any more than you have to be.  That is why I offer 2-3 day turnaround time on all ECU's and next day return 
shipping is included on all U.S. orders with valid UPS addresses.  I also believe in maintaining a good relationship 
with my customers.  I offer zero downtime re-flashes for existing customers.  If you need a reflash I will send out a
new program to you so that you don't have to wait.  All that I ask is that you drop the old chip back by...UPS ground.

TUNING OPTIONS

The tune will be written for your specific setup.  However I do have some limitations on what hardware I support. 

The following hardware is supported:

Mass Air Meters:
Z32 (N62) MAF
Maxima (N60) MAF
S13 SR20DET MAF
S13 KA24DE MAF

Injectors:
370 to 850cc side feed injectors
50# and 72# MSD top feed injectors

Cobra MAF is NOT supported. Q45 MAF is also NOT supported.  Not all MAF/Injector combinations are
supported.  if you have a non-standard combinaiton please contact me first.

Each tune is custom programmed for the modification list that you send me.  All tunes have the speed limiter 
removed and the rev limit can be changed to your specification.  If you do not know what the best rev limit for your 
setup is I can recommend a rev-limit setting for you.  All airflow limiters are also removed from each program. 
Maxima MAF is only available for 370cc and 480cc injector applications.  2-step rev limiter and flat shift 
modifications are also under development for all tunes.

requires an S13 KA ECU.

Turn around time is 1-2 days after I receive your ECU. All U.S. orders receive next day return shipping with a valid 
UPS address.  NO P.O. boxes or other addresses that are not shippable by UPS.

Payment is by Paypal.  Your account must have a CONFIRMED shipping address in order to be able to purchase. 
I will only ship back to the CONFIRMED address on the account used for payment.  If you are not able to purchase 
with Paypal please contact me and we can work out other arranngements.

Please include a complete list of engine, turbo and fuel system modifications in the comments area of the Paypal 
payment.  This is what you are paying me for...and what I will program the ECU for. 

Be as specific as you want in this section...but remember...if you want me to tune for it...LIST IT!!
