So id thought I'd share my experience with you all about my brilliant service with AJI Tuning. So it started off with me buying an AEM series 2 ems last summer, bought it cheap as it had a known fault showing max temperture on the display as soon as you turn the ignition on. My plan was to get it fixed and get a custom map for track and road keeping my car N/A, I wanted more mid range gains with lower vtec, the only engine related mods I have are J's decat and 60rs single exhaust. I got in touch with AJI Tuning and explained the situation i was in, he managed to remotely control my laptop, put a base map on there and then start the car up and check that everything else was okay with the ecu. The ecu was reading the temp correctly on the AEM tuner software, could watch it creep up as the engine was getting hotter. He said it would be something simple like a burnt out ground somewhere in the circuit.

So I got in touch with AEM in America and said about the issue I was having and got it sent off to them. I was getting updates from them via email and its progress. It was $100 to Inspect/Repair and sure enough it was a burnt sensor ground circuit. The turn around time was about 3-4 weeks from when I sent it off to receiving it back at home. So i got back in touch with AJI Tuning and before we began the mapping process I needed to install a wideband o2 sensor and gauge. I went for the AEM 30-4110 and installed the gauge where the audio controls were, haven't got many photos unfortunately. Once installed we started the mapping process.

He asked me what I required and what mods I had fitted and as above my aim was to have better mid range gains. He explained that I needed to log the partial throttle runs and wide open throttle runs so he could keep updating the maps and send them back to me to upload and do more runs until both of us were happy with how it was performing and I've gotta say it feels so good! It feels smooth and almost oem when normal driving but pulls when you put your foot down it made a big difference, feels like i can use more of the rev range now. I booked my s2k into the Dyno at Lloyd Specialist Developments for peace of mind and to see power figures, they used a hub type dyno. With the most aggressive tune it made 191 bhp at the hubs and 128 lbft. Typically they said you would roughly add around 45bhp to get your fly bhp so around 236 which seeing how its 2001 with 130,000 miles on the clock I thought was pretty good. The track tune was 185bhp at the hubs and 5 less torques but safer to run. They were impressed with how good tunes were and good air/fuel ratios. Managed to get out on track at castle combe a couple weeks back but unfortunately was pouring with rain so couldn't test the car properly but there will be more track days to come this summer, the nurburgring will be the real test later in the year!

So overall I'm very happy with what he's done for me, very knowledgable guy and was always willing to help when i wasn't sure about anything. I was very new to the ecu side of things but feel like I've learned a lot more now since the whole process. If anyone is looking for mapping or advice on mapping then get in contact with AJI Tuning, very reasonably priced also. I'll put his link down below:
