I am leaning toward a PFC with the banzai adapter for my FC. I am reading a lot (too much...) on the forum, and I am becoming more inclined to buy that ems. I just feel that there is a lot more support for this EMS than any other.

I am a noob, I never tuned an RX-7 myself, nor did I tuned any other engine, but I want to learn. I'd especially like to achieve my goals without breaking anything, if possible. To make this simple I'd like to know if its possible to tune my car myself and succeed the first time... I sincerely hope it's not a silly question, I know it won't be perfect the first time, but I would like to avoid toasting my engine. There is no tuners in my area, especially no rotary engine tuners.

I also noticed that the Vipec/Link EMS seemed fantastic for the price, but there seems to be no easily found technical support for it, which could be a draw back (I guess)

My current set-up:

FC
new engine harness
13b-re with aggressive streetport
straight through exhaust
HKS intake
T04R (might change it for a gt3574)
40mm Tial
unknown intercooler
Koyo aluminum

I absolutely want to keep the A/C, I am planning of using AI in a relatively near future. I currently have another engine, it's a stock TII, and I would probably do my experiences on this one before risking my brand new street ported engine...

So I'd like to know your opinions on my choice of EMS and if I can succeed by my own, without risking an engine.

Whenever anyone tunes there is a risk of blowing the engine, it does not matter what engine management system. Changing AFR and timing on any vehicle can cause damage. This is one of the reasons we do a full pre-tuning inspection all all cars that we have not previously worked on that come in for tuning. Just to make sure that all the other system are capable of supporting the tuning.

Can you tune yourself? Sure. You need to have the right equipment; wideband, datalogit, EGT, etc. Rent a dyno, as tuning on the street is a pain and extremely dangerous, since you will be constantly looking at the laptop and not the street.

I do not see any fuel system in your list of mods. Stock injectors and pump will not support what you are planning to do.

Could you Banzai-Racing (as an example) tune a car with a Vipec/link EMS even tho you are not used to that system? If you wouldn't it give me a hint of what I am getting into... And if you would I still consider it would be a steep learning curve for me to try it by myself.


I know its not in my list, it's because the engine is currently not in the car. I am buying everything pieces by pieces, so if its not on the list its just because I haven't bought it as of now. I got injectors (that came with a bunch of used parts), but I don't know their size so I am not sure I'll use them. I still need to buy a bigger fuel pump and rewire everything. But the car is currently almost stock. The project is still far from being complete.

I "could" tune any EMS, however I have been tuning for 20 years and have a firm grasp on what should and shouldn't be done. What needs to be done does not vary too greatly from one EMS to another. There are EMS systems I refuse to tune simply because they are too glitchy or the interface is trash. It is always a steep learning curve when you are dealing with a new software, for me or anyone else, however I have the experience to know what I should be looking for and the ability to extract problem areas from a dyno sheet and data logs.

I am not saying you can't (or shouldn't) tune it yourself, just that nobody can tell you that you will definitely get it right the first time without blowing your engine considering you have never tuned anything.

Hey, would it be smart to re-install the a/c that was taken out of an 87 rx7?

I'd say why not, if you are sure it's still functionnal. You also need to be sure you want to spend the amount of money necessary to make it functionnal again (the gaz, compressor and hoses are few hundred dollars) so you just need to know if its worth for you.

I am sure there is some info about that if you use the search function... A lot have been said about A/C, the EMS Forum is not the best area to find it tho.

Hahaha, i'm a newbie and couldn't make my own thread. but i'm looking to buy an 87 rx7 and i found one, it only needs a couple of things for it's safety, but the a/c system isn't installed, and all the work put into it was all done by the guy himself. He has all the parts he pulled out, but you can never be sure if it's functional until you test it. I'm really caught on 2 ends right now. I want an rx7 really badly, but at the same time, i don't want to pay the 4.5k he's asking for it and end up getting screwed over. Oh and it also has a rebuilt status, due to a minor front end collision, but it was all repaired. Is the price he's asking for it a fair price?

I know your are new here. I am not an old as hell member either. But you don't need to make your own thread to use the search function. Search button is straight in the center of the top banner, and in the right corner of every specific subjects and threads (search this forum).

If you are searching for a clean example, you'll need to pay for it. Best advice is to take your time, do a lot of research before buying it (to know what you are buying) and not try to save every penny by buying a cheap priced car and end up with too many problems for you to appreciate these old cars. Search is key and there is a lot of info over here to help you to understand what you are getting into.

Also try to post your questions in specific area. This is the EMS forum, it covers totally differents subjects that A/C, buying a used car, and fair prices for a used car. Here it's about tuning a standalone ECU replacing your stock computer.

Custom made set-up like the car listed on Kijiji may be a bad idea for you, if you don't know rotary engines.
