I would recommend Hondata over the piggy backs. You will make a lot more power. You have better control over the engine.
If you have both you can sell the AFC for $250 and the Map for $200.
That leaves you only $400 left.

I don't think so.wenlyone said:
Nope. No standalone engine management is street legal. If you're OBD-I, it doesn't matter what you run, they'll never know, since they don't plug into the service port. If you're OBD-II, there's nothing that's legal, not even a Hondata. As of now, Hondata requires you the use of an OBD-I ECU, which OBD-II service connectors will not identify, making them 100% illegal.wenlyone said:
Correct! I got the AEM EMS (not hocked up yet, waiting for dyno) because I'm OBD1! Sometimes I feel so lucky that I got an OBD1 because its so much easier on the emmisions, which is a bitch in CA!
I belive that the EFI (or whatever its called) that 4DoorGSR and GVTEC is using is smog legal (I think). 4DoorGSR lives here in the Bay Area so I would assume that his car is street legal since he's been driving around with it for a while now.
My good ol' friend neouser is planning on getting one too but not anytime soon. He was the one who told me about the emmisions stuff. And that is why he's streering away from Hondata and AEM because he has a 98 teg (OBD2).

EFI PMS is not legal, but they won't notice it, since it runs parallel to the stock ECU. It can either function only under boost, or it can completely bypass the stock ECU and use it's own fuel maps. BUT, the AEM EMS is still a better system, as it is a complete standalone ECU replacement...
I prefer the AEM over the Hondata because there is no need to burn new roms for new setups. Also you wouldn't have to buy all the extra accessories just to be able to get a good system. Stage 4 is equvilent to the AEM, but the AEM still comes out on top for better standard options.wenlyone said:
It is a little harder to work with, menaing you have to understand the dam thing, but when you do, you will find it a better tuning option than the Hondata.
Actually, yep, that's exactly what I'm saying. I'm not a big fan of the Hondata system. The prices for what you get are misleading. You can only get software with the Stage 4, and if you want to read Boost, you have to pay extra to get the "B" feature. If you're OBD-II, you have to get an adapter harness. Pain in the ass. You get a plug and play unit with the AEM EMS out of the box.wenlyone said:
If you're OBD-II, Hondata won't pass emissions either. People think that it will because it uses a stock Honda ECU. WRONG! Hondata only uses stock Honda OBD-I ECU's, which means that when you go into smog, after the scan the barcode on the frame of your car inside by the driver's side door, they will plug a cable into your service port. OBD-I ECU's will not send a signal to this cable. In order to pass smog in an OBD-II car, you must have an OBD-II compliant ECU. Since most aftermarket companies don't make them, just about every standalone is not smog legal. The exception, once again, is the EFI PMS. That runs parallel to the stock ECU. It has 3 modes of operation. Disabled, supplemental or full. In other words, you can disable it and use only your stock ECU, you can run it with your stock ECU and just have it map anything out of the ordinary (boost, nitrous, etc.), or you can have it bypass the ECU and run all your maps off of it, just like a full standalone. It does not alter signals going to the ECU like a piggyback. It actually has the capability to control the timing and injectors on it's own and has it's own set of maps.wenlyone said:
All the devices in question have base maps available from their respective companies that can be downloaded. AEM, EFI and Hondata (yuck!) all provide stock maps...
Yep, but it should still be done on a dyno with a wideband. The PMS comes with a little programming unit that's good for rough tuning. If you use the software that EFI sells, you can fine tune it and take advantage of it's built in datalogging capabilities! Awesome system, sells for under $1000.wenlyone said:
