engine mangament ???
I just stopped using Neptune 10 months ago, have not restarted the car since.... no bad taste I got to know James very well, good guy and there is nothing wrong with the program, just wasnt for me anymore......
I got my new style small frame AEM Box with UEGO and an EPM for $1250 BNIB.... FYI
I was a Neptune RTP owner for several years for starters, and before that I had an S300 and before that a hack. I was happy with Neptune but found myself wanting alot more from my ECU real quick.
Neptune is fine for street cars but it has huge downfalls (S300 as well) if you want to try and go fast and do it consistently, the lack of complete timing control, no COP capability, no in-depth tables and not to mention all the OEM ECU's are at a minimum of what now 14yrs old.
I had a hot start issue that could not be tuned out running Neptune, every time I shut my car off hot and restart it would run extremely lean for 30sec to a minute(checked everything), if I would of had AEM there is a table that can fix that... but with the OEM **** you just have to deal with it. there are alot of stupid querks with the OEM **** that made me want to spend the money to do it right...

Well, just for your own sake, the program has come a long way in the last 10 months....
Lol.... If it cant run COP, doesnt have enough tables to swim in, and not be run through a processor on an ECU board thats 14yrs old at the minimum.... it has not come far enough 
I have been following the progress.... always have.

lol... i just read this whole thread... comparing crome,ectune or neptune to any ems is like comparing oranges to apples... 2800$ for aem?? i just bought 2 boxes at 500$ each.. one was brand new one was bareley used... s300 is around 600 bux plus you need an ecu.. you cant run in excess of 10+ injectors on any honda ecu, you dont have boost comp tables, true anti lag, trac. control, etc.. i will agree, for 250$ crome or ectune is def worth it for something mild with stock ignition setups... ive tuned many cars over 500+ whp on stock honda ecu based programs. (ie.crome,hondata, ectune) but when people start going over excess of 45+ psi on bigger turbos, there is nothing like using the benefits of a full stand alone... just my 2 cents :thumbsup:
Oh, as for NepTune. I was one of the first to have the software and it has changed A LOT over the years. There has been some issues over the years but as it sits right now it works great. 100% of the cars I have done are just running on a chip with no RTP but they are mostly 300hp daily drivers or 200hp all motor cars that dont need any adjustments. I will be doing some RTP Demon tuning soon. Overall NepTune get a good vote.
For some, factory based ecus do everything they need it too. For others that need more, there are the standalones...
If the factory based ecus could do it all, there wouldnt be a need for more sophisticated ecus, BUT they CANT do it all. Thats where AEM/MOTEC/ETC come into play...
There have been many cases where changing to a standalone that can read hall effect sensors (T1 trigger/aem epm) have gained HP due to the fact the cam/crank signals are much cleaner than the factory sensors in the distributor resulting in more precise timing control...
This is another reason I plan on using AEM over factory ecu based tuning options...

i have a fully built motor now that will surely be 110+ traps and on top of that, i have the dope on the side..
I really hope one day you can grow up bro and stop with the immature responses.

Because bseries doesn't have CAM Angle sensors.
I do agree with the above stated tho..

1 cable for everything.. dont need all those wires anymore. I have some people who need to switch over but non the less yes.

I'd believe if you were boosting 45psi .. then yes, you'd want to get as close to your points of tuning as you would need too, with that amount of boost the smallest error could be .. failure.
they are having some issues we had a car at jeffs to test the obd2 boxes and it had some issues and i now felix was having some issues with his obd1 box but what jeff has told me they are being worked out asap..
Do you have any vids to back up your "facts"?



I have always been hesitant towards newly released AEM Electronics though.
